Liquids A and B form an ideal solution. The vapour pressure of A and B at 100$^{\large\circ}$C are 300 and 100 mm Hg respectively. Suppose that vapour above solution is composed of 1 mole of A and 1 mole of B is collected and condensed. This condensate is then heated at 100$^{\large\circ}$C and vapour are again condensed to form a liquid L. What is the mole fraction of A in the vapours of L?
