If two substances A and B have p_(A)^(@): p_(B)^(@) = 1:2 and have mole fraction in solution as 1:2 then mole fraction of A in vapour phase is

If two substances A and B have p_A^0 : p_B^0 = 1: 2 and have mole fraction in solution 1: 2, then mole fraction of A in vapours is

If two substance A and B have P_A: P_B=1 : 2 and also X_A : X_B in solutions as 1 : 2, then mole fraction of A in vapours is

Two liquids A and B have P_(A)^(0):P_(B)^(0)=1:3 at a certain temperature. If the mole fraction ratio of x_(A) : x_(B) = 1:3 , the mole fraction of A in vapour in equilibrium with the solution at a given temperature is :

Two liquids A and B have P_(A)^(@) and P_(B)^(@) in the ratio of 1:3 and the ratio of number of moles of A and B in liquid phase are 1:3 then mole fraction of A in vapour phase in equilibrium with the solution is equal to :
