How To Find Mole Fraction Of A Reaction

When concentration is expressed as the amount of solute per mass of solvent, the measurement is called molality. Mole fraction is another common concentration unit, and is given by the number of moles of solute per total number of moles of all solution components — solutes and solvent. Mole fractions are useful, for example, when investigating the "vapor pressure" of solutions. This reflects the extent to which solute and solvent particles "escape" from a liquid solution into the gaseous phase, as the mole fraction is equal to the ratio of partial pressures to total pressure. Now that you have an idea of how the concentration of a solution can be measured, let's go through a protocol for making a solution with a specific molar concentration. Mole fraction is not very useful for experiments that involve quantitative reactions, but it is convenient for calculating the partial pressure of gases in mixtures, as we saw in Chapter 10.

As you will learn in Section 13.5, mole fractions are also useful for calculating the vapor pressures of certain types of solutions. Molality is particularly useful for determining how properties such as the freezing or boiling point of a solution vary with solute concentration. Units of ppb or ppm are also used to express very low concentrations, such as those of residual impurities in foods or of pollutants in environmental studies.

They are used to store and handle small amounts of material, carry out chemical reactions, and develop materials with controllable properties. A solution is a homogeneous mixture containing some components in small amounts, called solutes, and one component in a large amount, called the solvent. The amount of solute relative to the total amount of a solution is known as its "concentration". In this video, we will first review the different types of units for measuring a solution's concentration.

We will then go through a protocol for making a sucrose solution. Finally, we'll look at how concentration measurement is used in diverse chemical applications. The properties of a solution are different from those of either the pure solute or solvent. Many solution properties are dependent upon the chemical identity of the solute. Compared to pure water, a solution of hydrogen chloride is more acidic, a solution of ammonia is more basic, a solution of sodium chloride is more dense, and a solution of sucrose is more viscous.

There are a few solution properties, however, that depend only upon the total concentration of solute species, regardless of their identities. These colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. This small set of properties is of central importance to many natural phenomena and technological applications, as will be described in this module. How do chemists decide which units of concentration to use for a particular application? For many applications this may not be a problem, but for precise work these errors can become important. In contrast, mole fraction, molality, and mass percentage depend on only the masses of the solute and solvent, which are independent of temperature.

Because solution volumes vary with temperature, molar concentrations will likewise vary. When expressed as molarity, the concentration of a solution with identical numbers of solute and solvent species will be different at different temperatures, due to the contraction/expansion of the solution. More appropriate for calculations involving many colligative properties are mole-based concentration units whose values are not dependent on temperature. One may wonder why so many different measures of solution concentration exist. The answer lies in the many applications of solutions and the many orders of magnitude over which concentrations span. Although molarity is a convenient measure of concentration for stoichiometry calculations involving chemical reactions, molality is more appropriate in studies of certain colligative properties.

Properties of a solution that depend only on the concentration of solute particles are called colligative properties. They include changes in the vapor pressure, boiling point, and freezing point of the solvent in the solution. The magnitudes of these properties depend only on the total concentration of solute particles in solution, not on the type of particles. The total concentration of solute particles in a solution also determines its osmotic pressure.

This is the pressure that must be applied to the solution to prevent diffusion of molecules of pure solvent through a semipermeable membrane into the solution. Ionic compounds may not completely dissociate in solution due to activity effects, in which case observed colligative effects may be less than predicted. There are several different ways to quantitatively describe the concentration of a solution. For example, molarity was introduced in Chapter 4 as a useful way to describe solution concentrations for reactions that are carried out in solution. Mole fractions, introduced in Chapter 10, are used not only to describe gas concentrations but also to determine the vapor pressures of mixtures of similar liquids.

Example 4 reviews the methods for calculating the molarity and mole fraction of a solution when the masses of its components are known. In the solid, crystalline form glucose molecules are also ordered into a three dimensional array, as in the case of the NaCl crystal lattice discussed above. However, unlike in the case of NaCl, in which the compound breaks apart into smaller components , the glucose molecule remains intact as a single molecular unit in solution. The figure below is a schematic of the glucose molecule dissolved in water. Each glucose molecule is surrounded by a certain number of water molecules; therefore in solution, the glucose solid broke apart, but the glucose molecules themselves remained intact.

Note that the definitions of molarity, molality, and mole fraction are the same for both molecular and nonmolecular solutions. You will learn more about interactions between molecules in Chemistry 111. A schematic of the glucose molecule in aqueous solution. Noting that the atomic mass of hydrogen is 1 amu and that of oxygen is 16 amu, the molar mass of acetone is 58 grams.

That means the total number of moles in solution is 1.84. Now you're ready to calculate mole fractions using the mole fraction equation. Mole fractions can be generated from various concentrations including molality, molarity and mass percent compositions. When immersed in water, many solids break apart into particles surrounded by water molecules. This process of dissolution converts a heterogeneous mixture of solid and liquid into a single homogeneous mixture consisting of liquid water and dissolved solute particles.

The dissolution process for sucrose can be written as a chemical equation using the solid and aqueous phase designators. The designator following a species implies that water molecules are surrounding and solvating that species. The concentration of a solution can be expressed in a number of different units, each of which may be more suitable for particular applications than others. One of the most commonly used units is molarity, which is the amount of solute per volume of solution; one molar is equivalent to one mole of solute per liter of solution. Due to the simplicity of measuring the volumes of liquids, molarity is one of the most convenient units for stoichiometric calculations of reactions in solution.

Stoichiometry is based on the number of molecules involved in a reaction. Therefore, knowing the molarity simplifies the calculation of required reagents. Chemical reactions are always balanced using moles of the reactant and the product. The concentration of a solution involves the mole of a solute. Some examples are molar concentration or molarity, molality, mole fraction, molar density.

The mole fraction is another way of expressing the concentration. Mole fraction and mass fraction are used to express the relative fractions of different constituents in a mixture. Both are unit-less terms since the ratios have the same unit, and thus the units cancel out. Mole fraction is a measure of concentration of a chemical solution. It can be calculated by dividing the number of moles of one component of a solution by the total number of moles of all components of the solution. The sum of mole fractions of all components in the solution is always equal to 1.

Mole is the number of fundamental units of reactant substances involved in a chemical reaction whereas the fraction is referred to as the division of proportion of the reactant substances, respectively. Therefore, we can say that Mole Fraction equation is the ratio of the reactant substances that react/combine to form a product. The mole ratios calculator is the best way to calculate mole fraction instantly. When analyzing solutions, chemists measure concentrations of components in moles. The mole fraction of a solute is the ratio of the number of moles of that solute to the total number of moles of solute and solvent in solution. Because it's a ratio of moles to moles, the mole fraction is a dimensionless number, and of course, it's always less than one.

The free and best mole fraction calculator helps you to calculates the mole fraction, moles of solute, and moles of solvent according to the given inputs. This mole fractions tool is quite easy to use which makes mole fraction calculation very simple and interesting. One major benefit of the behavior of gases is that the volume of one ideal gas in a mixture of ideal gases is equivalent to its mole fraction.

How To Find Mole Fraction From Chemical Equation For all practical purposes, the volume fractions and the mole fractions of the components of an ideal gas mixture are interchangeable. Equilibrium constants which is expressed in terms of the mole fraction and partial pressure is symbolized as Kx, for both homogeneous and heterogeneous reactions involving gases. If we have a mixture of gases (A, B, C, etc.), then the mole fraction of gas A is worked out by dividing the number of moles of A by the total number of moles of gas.

This page explains equilibrium constants expressed in terms of partial pressures of gases, Kp. It covers an explanation of the terms mole fraction and partial pressure, and looks at Kp for both homogeneous and heterogeneous reactions involving gases. The mole fraction of any component of a mixture is referred to as the ratio of the number of moles of that substance to the total number of moles of all substances present. When it comes to the mixture of gases, the partial pressure of each gas is said to be as the product of the total pressure and the mole fraction of that gas. Dissolving a nonvolatile substance in a volatile liquid results in a lowering of the liquid's vapor pressure.

This phenomenon can be rationalized by considering the effect of added solute molecules on the liquid's vaporization and condensation processes. To vaporize, solvent molecules must be present at the surface of the solution. The presence of solute decreases the surface area available to solvent molecules and thereby reduces the rate of solvent vaporization. While this interpretation is useful, it does not account for several important aspects of the colligative nature of vapor pressure lowering.

A more rigorous explanation involves the property of entropy, a topic of discussion in a later text chapter on thermodynamics. A lower vapor pressure results, and a correspondingly higher boiling point as described in the next section of this module. Most chemical reactions are run in solution because dissolved solutes are mobile enough to rapidly mix and bump into one another.

Solutions can also be used to store small amounts of solutes in macroscopic and easily handled volumes. Solutions exhibit some interesting physical properties called colligative properties that can be attributed to the entropic effects of dissolving a solute in a solvent. What are the mole fractions of HNO3 and water in a concentrated solution of nitric acid (68.0% HNO3 by mass)? This phenomenon can be rationalized by considering the effect of added solute molecules on the liquid's vaporization and condensation processes. While this kinetic interpretation is useful, it does not account for several important aspects of the colligative nature of vapor pressure lowering.

In other words, the division of the number of moles of the solute with the number of moles of both solute and solvent is equal to the mole fraction of the respective solute in a chemical reaction or solution. Using the mole ratios calculator is helpful while calculating it online. A mole fraction, as the name implies, is a comparison of the number of moles in solution. It is found by taking the number of moles of solutes divided by the total number of moles (solutes + solvent).

The molarity is the number of moles of solute per liter of solution. Molarity is defined as the number of moles of solute per unit volume. The molarity is reported as M , which is mol of solute/L of solution. Molarity is temperature dependent as the volume of the density of a solution typically changes with temperature.

We use the total pressure of the gas in Equation 4.18 and not the partial pressure because we are using the volume fraction based on the total volume and total pressure of our system. If we used the total volume of the system instead of the volume fraction, then we would use the partial pressure of the gas and Equation 4.18 would look something like Equation 4.21. Solutions whose components have significantly different vapor pressures may be separated by a selective vaporization process known as distillation. Consider the simple case of a mixture of two volatile liquids, A and B, with A being the more volatile liquid. By appropriately heating the mixture, component A may be vaporized, condensed, and collected—effectively separating it from component B.

Concentration of reagents, solvent components, and other components of a chemical reaction often have significant impact on the rate of products of the reaction. Higher reactant concentrations increase the likelihood that the molecules will encounter each other and react, thus potentially increasing the reaction rate. At the same time, increased concentrations of charged salt ions in solution may also favor the aggregation of hydrophobic, or "water-repelling" molecules. In this example, 100 mL of a 0.01 M sucrose solution is being made, so 0.342 g will be needed.

To weigh out the required mass of sucrose, first place a clean, empty weigh boat on the balance. Set the "tare weight", which means setting the weight of the empty weigh boat as zero. Then, using a scoopula, transfer the sucrose powder from the reagent bottle onto the weigh boat until the desired amount is obtained.

Place a powder funnel into a clean, dry 100-mL volumetric flask. Using a wash bottle containing the solvent, in this case distilled water, rinse any remaining solid from the weigh boat into the flask. Multiplying the mole fraction by 106 gives the parts per million concentration, the number of solute particles per million particles of solution. The number of moles of solute per liter of solution, or molarity , is a second common measure of concentration. In ideal gases, the mole fraction is defined as the ratio of the mixture's partial pressure to its total pressure. The mass fractions of all components is equal to 1 since the mass fraction is a ratio.

The mass fractions of individual components are always lower values than 1. Mass fraction can be given as mass percentage as well. In elemental analysis calculations, mass fraction refers to the ratio between the mass of a chemical element and the compound. The mass fraction is independent of temperature because mass does not change when the temperature is changed.

Now you should have a good understanding of solutions and the solvation process for ions in aqueous solutions. You need to be comfortable with using molarity, molality and mole fractions. Also you should know the definitions pertaining to solutions. In a mixture of ideal gases, the mole fraction can be expressed as the ratio of partial pressure to total pressure of the mixture. Generally, scientists calculate the mole fraction in terms of moles of the substance. However, the mole fraction expresses the ratio of moles of a compound to the total moles of the mixture.

The mole fraction is indicated the amount of moles of a solute divided by the total amount of moles of the solution. Sometimes, the mole fraction is also named as the amount fraction. According to the chemistry, it is said to be identical to the number fraction that is stated as the number of molecules of a constituent divided by the total number of all molecules. To calculate the mole fraction, you can try our mole fraction calculator. Osmotic pressure and changes in freezing point, boiling point, and vapor pressure are directly proportional to the number of solute species present in a given amount of solution. Consequently, measuring one of these properties for a solution prepared using a known mass of solute permits determination of the solute's molar mass.

Is Barnard College Worth It

Barnard is one of a handful of outstanding colleges exclusively for women. The entrance standards at Barnard are very tough, but the Admissions process is definitely less competitive than Columbia's. For example, though Barnard matriculates about 550 students per year, it admits 23% of its applicants. Columbia, by contrast, only accepts about 7% of its applicants! Now once enrolled, Barnard and Columbia seemingly intersect everywhere. Note that they do NOT share dorms, but the Freshman orientation program is completely co-mingled.

So yes, I would probably recommend that a student who is in love with Columbia, but not quite qualified to be in the top 25% of the Columbia applicant pool look seriously at Barnard. They are both elite with incredible and strong alumni networks . For those who qualify (academically and 'financially) and fit , either school is a winner.

Barnard is a small, highly selective liberal arts college for women located in New York City. The student body of just over 2,650 is part of a diverse and close-knit community and students study with leading scholars who serve as dedicated, accessible mentors and teachers. Founded in 1889, Barnard also engages in a unique partnership with Columbia University, situated directly across the street.

Students have access to cross-registration of courses with Columbia, many joint extracurricular activities, participate in NCAA Division I Ivy League athletics and enjoy a fully coed social life. The location in New York City grants students access to thousands of internship opportunities in addition to unparalleled cultural, intellectual and social resources. Barnard's diverse student body includes residents from nearly every state and more than 55 countries worldwide. About 40 percent of the student body identify as students of color, and 11 percent are non-US citizens or permanent residents. As of 2012 Barnard pays Columbia about $5 million a year under the terms of the "interoperate relationship", which the two schools renegotiate every 15 years.

Despite the affiliation Barnard is legally and financially separate from Columbia, with an independent faculty and board of trustees. It is responsible for its own separate admissions, health, security, guidance and placement services, and has its own alumnae association. Nonetheless, Barnard students participate in the academic, social, athletic and extracurricular life of the broader University community on a reciprocal basis. The affiliation permits the two schools to share some academic resources; for example, only Barnard has an urban studies department, and only Columbia has a computer science department.

Most Columbia classes are open to Barnard students and vice versa. Barnard students and faculty are represented in the University Senate, and student organizations such as the Columbia Daily Spectator are open to all students. Barnard students play on Columbia athletics teams, and Barnard uses Columbia email, telephone and network services. Luckily, unlike some Seven Sisters schools and other all-women liberal arts colleges in the country, students at Barnard are not required to live on-campus.

This means that they can deduct $15,691 from the sticker price if they wish to live elsewhere, bringing the total cost from $76,279 down to $60,588. Barnard College is liberal arts college based in New York City, United States. It is a private college which was named after the 10th president of Columbia University, Frederick Barnard, and is currently one of the renowned names in theUS Education System.

It is one of the selective colleges with an average acceptance rate of 13%. Barnard College enrolls around2,682studentsincluding 11% international students from 57 countries aspiring tostudy in the US. Founded in 1889, Barnard is a small liberal arts and sciences college for women. Our faculty is comprised of leading scholars who serve as dedicated, accessible teachers to our diverse community of 2400 extraordinary women. The College's metropolitan location grants students access to thousands of internships in addition to excellent cultural, intellectual, and social resources. Barnard students graduate from the University, though we remain an independent institution.

Georgia Institute of Technology, often referred to as "Georgia Tech," is a located in Atlanta, Georgia. The school offers technology-focused education to more than 25,000 undergraduate and graduate students across six colleges and 28 schools focusing on business, computing, design, engineering, the liberal arts and sciences. If you want to have friends, you have to be able to go to the bars and out to eat and pay for clubs or pay to be in greek life. I was constantly stressed about money every single day I was at this school, and the people around me literally were a level of rich I did not even know existed. I definitely made a few good friends, but I truly found like maybe 2 people the ENTIRE time I was there that came from a similar (working/middle class, rural or small town) background like I did. Everyone knows you are not one of them, even if you don't.

And very few other people I knew had jobs, so I felt alone in that too. There are definitely other girls like me there, but it was NOT the majority. Basically, I would say if you are a regular person, you will feel extremely stressed out and subtly isolated at this school. Through an agreement with List College of the Jewish Theological Seminary, located just north of the campus at 122nd Street, students can apply to simultaneously earn a BA degree from Barnard and a BA at JTS.

Barnard also offers highly-talented music students the opportunity to apply for the Lesson Exchange Program with Juilliard and/or the Cross Registration Program with the Manhattan School of Music. Both programs will require a separate application and audition. The Lesson Exchange at MSM and Juilliard provide private weekly lessons with faculty.

It is important to note that the Exchange does not include participation in large ensembles. Students in the Juilliard program can take classes in instrumental or vocal performance and piano composition. MSM students can take lessons for instrumental or composition only. Barnard does also offer a multitude of music courses, major, private lessons and many performance opportunities through its own music department and at Columbia. "Small liberal college in the best city in the world with all the perks of a big university across the street," is exactly what admissions office will tell you and they're right.

If you love the city, but still want a campus that feels like home... If you want to be surrounded by the most intelligent, driven women you'll ever meet in your life... If you want all the resources of a huge university, but the care and attention of a small school... If you want a solid liberal arts base, but the opportunity for great work experience during your time in college... If you want to feel like you're part of a greater legacy and network of alumnae... In 1955, few American colleges offered financial aid, and access was restricted, as a result, to those who could pay—typically, white, Anglo-Saxon, relatively wealthy families.

Today, by contrast, higher education is firmly and proudly committed to opening its doors to capable students from all family backgrounds and socioeconomic statuses. This is a very good thing, in my opinion, probably the most critical development in higher education of the last century. At Barnard, as at most of our peer schools, nearly half the student body receives some form of financial aid. The cost of this achievement is $34 million a year, or nearly 25 percent of our total budget. But it is a very real cost, and one that cannot be contained without limiting access. Barnard is amazing because it is a small liberal arts college with an abundant of resources, services, and support.

It gives students the best of both worlds- a huge research university experience and a small student-centered liberal arts college experience. The community on campus is warm and welcoming, and the intellectual debate and dialogue is rigorous and stimulating. There is a ton of school pride, and most students are thrilled to be here and love it. At the current published rates, an estimated total tuition, fees and living expense price for a 4 year bachelor's degree at Barnard is $312,176 for students graduating in normal time.

This methodology for estimating the 4 year cost is a straight multiple of the most recent reported annual total cost and does not factor in tuition increases during the time you're in school. It also assumes you receive no grant or scholarship aid and pay the full list price. The academics at Barnard College offer students a traditional liberal arts education, putting the emphasis on exploring the world from a wide variety of perspectives in a multitude of disciplines. The objective for a Barnard student is to develop her individual vision of how she can uniquely shape the world, and help her determine what her role could be within that vision. Barnard teaches their students how to think critically both inside and outside of the classroom in the sciences, humanities, social sciences, the arts, and world languages.

This is an academic program for brave young women who constantly exchange ideas without being afraid to take risks both intellectually and creatively. This highly respected liberal arts college is based in Williamstown, Massachusetts. All Williams students take at least two writing-intensive courses as well several courses in the arts and humanities, social sciences, and science and mathematics. Williams enrolls approximately 2,000 undergraduate students. Sometimes when I tell people I go to Barnard they're like "Oh...how do you like it being around all girls?" but I don't really feel like I go to a women's college.

While the freshman dorms are single-sex, all my classes and extracurriculars have guys in them and I have several guy friends from Columbia. Your experience can be more or less "Barnard" or "women's college" depending on your own decisions and wants. I liked the balance between having an entire city at my doorstep and having the quiet, intimate retreat of the Barnard campus to come back to. The campus is physically very small, but it doesn't feel this way, because you have access to space, activities, and resources across the street at Columbia. One potentially uncomfortable aspect of going to Barnard is the ambiguous relationship between Barnard and Columbia, which the administration does a pretty poor job of defining. When I tell people I went to Barnard, I often get the question, "Oh, so, is that like, the same thing as Columbia?" The answer I give them is no, it's not, it is its own college with its own philosophy of higher education.

But, being affiliated with Columbia University, it offers students the opportunity to take Columbia courses, participate in Columbia student groups, use the Columbia libraries, and just hang out on the Columbia campus. The way I see it, every student can choose her own balance between Barnard and Columbia life and find some satisfying meeting point between the two worlds. It's a great liberal arts college focused on goal oriented women's success. All of the administration wants to help and be accessible to the students. Barnard students, for the most part, while having a competitive edge, want to help each other.

People think it's great when you tell them you go to Barnard, although initially between Columbia College Students and Engineering students, there may be a little tension. I don't spend all of my time on campus, there's lots to do in the city, and I view seeing the city as part of my education. The big picture is that Barnard is an all women's college in the middle of New York City.

It's small, but you still get the big city atmosphere by just stepping out of the gates. You get the comfort of a school really dedicated to helping women be successful and you get to use all the resources of Columbia University. There is a lot of pride at Barnard and I don't see why there shouldn't be. It is discouraging sometimes when people ask me where I go to College and when I tell them they don't even know or they reply by saying, "You go to an all women's college?!?!" But I just set them straight.

The second consideration after understanding the cost of college is determining how to finance it. Some students are fortunate enough to have some form of family financial assistance, but student loans end up financing a significant portion of higher education in the U.S. 29% of Barnard College students receive U.S. Federal Student Loans with an average annual Federal Loan aid amount of $3,621. Other loans, or private loans, are the last resource students turn to when paying for college. They're the least preferable form of financial aid because they have higher interest rates and cost students the most money in the long run.

High percentages or amounts of federal loans still isn't a great sign - again, you don't want to see students burdened with too much debt. Generally, schools with strong financial aid programs will have students with more federal loans than private loans. It is a liberal arts college but because of Columbia across the street Barnard students get both a small community and a larger university. And in all honesty, Barnard truly does feel like a little more independent undergraduate college of Columbia University, it's a pretty close relationships.

They speak their mind and stand up for what they believe in. It's rare to find a Barnard student who doesn't express what she feels articulately in a class. The best thing about Barnard is that whatever interest you have, you will always find means to develop that interest. If you are interested in a certain career, you can use the funding that school provides through the Office of Career Development to attend conferences or get paid for a non-paid internship.

Another great thing is that if you don't have enough money to pay for your tuition, they will try to do everything to help you in terms of scholarships, grants and low interest loans. The school is just the right size, it is small enough to provide personal help and support, however, it supplies lots of resources within big campus of Columbia University. Most of my time on campus I usually spend, in libraries, of which there is plenty, beautiful college lawns in spring, campus caffe's and in nearby restaurants.

Barnard's administration is really great-everyone is very helpful. Just as the admissions office will tell you over and over - Barnard is the best of both worlds, a small college in a big city. Some people spend most of their time in the Barnard/Columbia/Morningside Heights area while others prefer to spend more time adventuring into the New York. The community can be what you make of it, if you want to find a large, close-knit, group of friends you will be able to.

If you prefer to have one or two close girl friends, you can do that to. The community is a good size, Barnard is small but if you ever feel claustrophobic, Columbia is a much larger community right across the street. Most people hangout on campus in the dorms, or in the Diana Center . A lot of people also choose to hangout at Columbia, in the libraries or the student center over there.

Barnard has a lot of "Barnard Women" pride, but not a lot of pride in the traditional sense. If you really want a rah-rah campus with tons of pride for athletic events and school-sponsored functions, Barnard/Columbia is not the place for you. I love pretty much everything about Barnard, I think its great that you can get the benefits of a women's college without having to sacrifice men. Barnard College, a private women's liberal arts college in New York City, is #51 among schools in the Veritas Prep Elite College Rankings and is one of the most selective women's colleges in the United States. Founded in 1889, the four-acre urban campus is adjacent to Columbia University in New York City's Manhattan neighborhood.

Barnard has a complicated relationship with Columbia University, being both a wholly independent entity with its own governance, and also a college within Columbia. Barnard students graduate with Columbia University diplomas that are signed by the Presidents of both colleges. Furthermore, Barnard College has a strong financial aid program. The lower your income is, the more help you can expect to receive in need-based grants. Because it's not a top-tier program, you may still have to find other ways of paying, like taking student loans or working, but you can expect to receive good support.

The "Cost of Attendance" is the total amount of money the average student has to pay, WITHOUT any financial aid, to attend a particular school. It includes not just Barnard College tuition and fees, but also room, board, textbooks, and personal expenses. Barnard college is one of the most unique college experiences that exist- partly because of it's location in NYC, partly because of the affiliation with Columbia, and partly because of its existence as a women's college.
