The vapour pressure of mixture of toluene and xylene at `90^(@)`C is 0.5 atm. If at this temperature 400 mm and 150 mm respectively then what will be the mole fraction of toluene in mixture ?

The vapour pressure of benzene and pure toluene at 70^(@)C are 500 mm and 200 mm Hg respectively. If they form an ideal solution what is the mole fraction of benzene in a mixture boiling at 70^(@)C at a total pressure of 380 mm Hg?

Benzene and toluene form ideal solution over the entire range of composition. The vapour pressure of pure benzene and toluene at 300 K are 50.71 mm Hg and 32.06 mm Hg respectively. Calculate the mole fraction of benzene in vapour phase if 80 g of benzene is mixed with 100 g of toluene.
