Assignment #3. The temperature of pure water at equilibrium vapor pressure of 36.2 torr is 45°C. When 30.4 g of a nonelectrolyte solute is dissolved in 40 g water, the vapor pressure of the solution is 3.20 lower than that of the pure water at the same temperature, what is the mole fraction, and molecular mass of the solute?

A patient has a “cholesterol count” of 214. Like manyblood-chemistry measurements,this result is measured inunits of milligrams per deciliter (mgdL1). Determine the molar concentration of cholesterol inthis patient’s blood, taking the molar mass of cholesterolto be 386.64gmol1. Estimate the molality of cholesterol in the patient’sblood. If 214 is a typical cholesterol reading among men inthe United States, determine the volume of such bloodrequired to furnish 8.10 g of cholesterol.
