Worksheet: Vapor Pressures of Solutions

In this worksheet, we will practice using Raoult's law to calculate the lowering of solvent vapor pressure by nonvolatile solutes.


A solution contains 6.00 g of urea, C O ( N H ) 2 2 , a non-volatile compound, dissolved in 0.100 kg of water at 2 5 C . If the vapor pressure of pure water at 2 5 C is 23.7 torr, what is the vapor pressure of the solution?
