In an ideal binary solution of "A" and "B" ,when equal mole fraction of "A" and "B" are present then total vapour pressure of solution in "760mm" of Hg.If vapour pressure of "A" in pure state is "600mm" of Hg then vapour pressure of "B" in pure state will be

At 27^(@)C .the vapour pressure of an ideal solution containing 1 mole of A and 1 mole and B is 500 mm of Hg . At the same temperature, if 2 mol of B is added to this solution the vapour pressure of solution increases by 50 mm of Hg . The vapour pressure of A and B in their pure states is respectively.

Two liquids A and B are mixed to form an ideal solution. The totol vapour pressure of the solution is 800 mm Hg. Now the mole fractions of liquid A and B are interchanged and the total vapour pressure becomes 600 mm of Hg. Calculate the vapour pressure of A and B in pure form. (Given : p_(A)^(@)-p_(B)^(@)=100 )

At 300 K, the vapour pressure of an ideal solution containing 1 mole of A and 3 moles of B is 500 mm Hg. At the same temperature, 2 moles of B are added to this solution. The vapour pressure of solution increases by 10% of the original vapour pressure. Correct statements about the vapour pressure are

If P_(A) is the vapour pressure of a pure liquid A and the mole fraction of A in the mixture of two liquids A and B is x, the parial vapour pressure of A is:

Two liquids A and B form an ideal solution of 1 mole of A and x moles of B is 550 mm of Hg. If the vapour pressures of pure A and B are 400 mm of Hg nd 600 mm of Hg respectively. Then x is-
