At 60 °C, the vapor pressure of pure benzene is 384 torr , and that of pure toluene is 133 torr . A mixture is made by combining 1.20 mol toluene with 3.60 mol benzene. Find:

(a) The mole fraction of toluene in the liquid.

(b) The partial pressure of toluene above the liquid.

(c) The partial pressure of benzene above the liquid.

(d) The total vapor pressure.

(e) The mole fraction of toluene in the vapor phase. Strategies are included with each section.
