Someone pls help me, I need the answer ASAP!!
Pure A (liq) has vapour pressure at 421 K is 80.1 kPa, and pure B (liq) is 61.2 kPa. The two substance form ideal liquid and gaseous mixtures. If the equilibrium composition of a mixture is established, in which the mole fraction of A in the vapour is 0.410, Calculate:
(a) The total pressure of the vapour.
(b) The composition of the liquid mixture.
