At 800C, the vapour pressure of pure liquid 'A' is 520 mm Hg and that of pure liquid 'B' is 1000 mm Hg. If a mixture solution of 'A' and 'B' boils at 800C and 1 atm pressure, the amount of 'A' in the mixture is (1 atm = 760 mm Hg) i. 48 mol percent ii. 50 mol percent iii. 52 mol percent iv. 34 mol percent
