A solution at `20^(@)C` is composed of `1.5 mol` of benzene and `3.5 mol` of toluene. If the vapour pressure of pure benzene and pure toluene at this temperature are `74.7` torr and `22.3` torr, respectively, then the total vapour pressure of the solution and the benzene mole fraction in equilibrium with it will be, respectively:
