319510 An ideal mixture of liquids A and B with 2 mol of A and 2 mol B has a total vapour pressure of 1 atm at a certain temperature. Another mixture with 1 mol of A and 3 mol of B has a vapour pressure greater than 1 atm. But if 4 mol of C are added to the second mixture, the vapour pressure come down to 1 atm. Vapour pressure of C, \({\rm{P}}_{\rm{C}}^{\rm{o}}{\rm{ = 8}}{\mkern 1mu} {\mkern 1mu} {\rm{atm}}\). Calculate the vapour pressure of pure A and pure B.

319511 The vapour pressure of pure liquid ‘A’ at \({\rm{310^\circ C}}\) is 120 torr. The vapour pressure of this liquid in solution with liquid B is 72 torr. Calculate the mole fraction of ‘A’ in solution if the mixture obeys Raoult’s law.

319512 Benzene and Napthalene form ideal solution over the entire range of composition. The vapour pressure of pure benzene and naphthalene at 300 K are 50.71 mm of Hg and 32.06 mm of Hg respectively. What will be the mole fraction of benzene in vapour phase if 80 g of benzene is mixed with 100 g of naphthalene?
