What is the vapor pressure of a solution in which the mole fraction of the solute is 0.200 and the vapor pressure of the pure solvent is 100.0 torr? (Assume a single nonvolatile, nonelectrolyte solute).
a. 0 torr
b. 80.0 torr
c. 100.0 torr
d. 120.0 torr
e. 20.0 torr
Answers: 3
= vapor pressure of pure solvent = 100.0 torr
= vapor pressure of solution = ?
= mole fraction of solute = 0.200
