Chapter 12, Problem 130P

(choose chapter or problem)

Liquids A (molar mass 100 g/mol) and B (molar mass 110 g/mol ) form an ideal solution. At \(55^{\circ} \mathrm{C}\), A has a vapor pressure of 95 mmHg and B has a vapor pressure of 42 mmHg. A solution is prepared by mixing equal masses of A and B.

(a) Calculate the mole fraction of each component in the solution.

(b) Calculate the partial pressures of A and B over the solution at \(55^{\circ} \mathrm{C}\).

(c) Suppose that some of the vapor described in (b) is condensed to a liquid in a separate container. Calculate the mole fraction of each component in this liquid and the vapor pressure of each component above this liquid at \(55^{\circ} \mathrm{C}\).
