At 334K the vapour pressure of benzene (C_(6)H_(6)) is 0.526 atm and that of toluene (C_(7)H_(8)) is 0.188 atm. In a solution containing 0.500 mole of benzene and 0.500 mole of toluene , what is the vapour pressure of toluene above the solution at 334K ?

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 vapour phase which is in equilibrium with a solution of benzene and toluene having a mole fraction of toluene 0.500 is (vapour pressure of pure benzene and pure toluene are 110 torr and 37.0 torr respectively at the same temperature).
