Solution: The van't Hoff factors are a function of the concentration and are often lower than the theoretical value. Would you expect a larger or smaller deviation from the theoretical value as a solution gets. Problem. The van't Hoff factors are a function of the concentration and are often lower than the theoretical value. A Member of the Grossmont-Cuyamaca Community College District ... Dr. Kimberly Olsen 1.0 Credit. Chemistry is the study of the structure and composition of matter that makes up living things and their environment. Chemistry also deals with the study of the changes of matter and the mechanisms by which changes occur. This course is recommended for college-bound students. This class cover topics such as matter, chemical reactions,... Osmotic pressure is a colligative property that can be used to determine the molar mass of an unknown substance. The osmotic pressure is determined by measuring the height of the column of solution and converting this value to mm of Hg (1 mm Hg = 1 torr, 760 torr = 1 atm). Using, Π V solution = n solute R T (where Π is the osmotic pressure, R
Problem : What is the vapor pressure of the pure solvent if the vapor pressure of a solution of 10 g of sucrose (C 6 H 12 O 6) in 100 g of ethanol (C 2 H 6 O) is 55 mmHg? To solve this problem, we will use Raoult's law: Then rearrange the equation to solve for the pressure of the pure solvent, P o. After converting the gram amounts to moles we find that the mole fraction of the solvent ethanol is 0.975.
Colligative Properties Worksheet 1) If I add 45 grams of sodium chloride to 500 grams of water, what will the melting and boiling points be of the resulting solution? Kb(H2O) = 0.52 0C/m and K f(H2O) = 1.86 0C/m. 2) What is the vapor pressure of the solution in problem #1 at 250 C? The vapor pressure of pure water at 250C is 3.17 kPa.
CHEMFILE MINI-GUIDE TO PROBLEM SOLVING CHAPTER 16 Colligative Properties Colligative properties of solutions are properties that depend solely on the number of particles of solute in solution. In other words, these properties depend only on the concentration of solute particles, not on the identity of those particles. ~Practice Worksheets (These are optional worksheets that will give you extra practice on different topics. I have the keys to the worksheets available in class.) Vapor Pressure and Boiling Worksheet

A 2009 practice quiz 1 from the TAs A 2009 practice quiz 1 answer key from the TAs Worksheet 3 from 2009: 10 questions on colligative properties and 10 questions to introduce you to chemical equilbria Answer Key Worksheet 3 from 2009: 10 questions on colligative properties and 10 questions to introduce you to chemical equilbria Colligative properties are dependent only on the number of particles in a solution, and not their identity. Some examples of colligative properties are vapor pressure, boiling point, freezing point, and osmotic pressure. There is a direct relationship between the boiling point elevation and the number of particles present in a solution.
