Question

At 300 K, the vapor pressure of pure benzene (C6H6) is
0.1355 atm and the vapor pressure of pure n-hexane
(C6H14) is 0.2128 atm. Mixing 50.0 g of benzene with
50.0 g of n-hexane gives a solution that is nearly ideal.
(a) Calculate the mole fraction of benzene in the solution.
(b) Calculate the total vapor pressure of the solution at
     300 K.
(c) Calculate the mole fraction of benzene in the vapor in
     equilibrium with the solution.
