Question

The resulting solution of mixing two liquids A and B behaves like an ideal solution. If 2 moles of A is mixed with 4 moles of B, then the vapour pressure of the solution at a certain temperature becomes 0.2 atm. If vapour pressure of pure A liquid at that temperature is 0.35 atm, then what will be the vapour pressure of pour B liquid?
