Calculate the mole fraction of toluence in the vapour phase which is in equilibrium with a solution of benzene and toluene having a mole fraction of toluene 0.50. The vapour pressure of pure benzene is 199 torr, that of toluene is 37 torr at the same temperature.

The mole fraction of toluene in the vapour phase which is in equilibrium with a solution of benzene (P_(B)^(@)=120 "torr") and toluene (P_(T)^(@)=80 "torr") having 2.0 mol of each, is
