The vapour pressure of a liqid solution containing A and B is 99 torr. Colculate mole % of B in vapour phase. (Given : P_(A^(@)) = 100 torr , P_(B^(@)) =80 torr)

The vapour pressure of a liquid solution containing A and B is 99 torr. Calculate mole % of B in vapour phase. (Given : P_(A^(@)) = 100 torr , P_(B^(@)) = 80 torr)

The vapour pressure of a liquid solution containing A and B is 99 torr. Calculate mole % of B in vapour phase. (Given : P_A^0 = 100 torr , P_B^0 = 80 torr)

2 moles each of liquids A and B are dissolved to form an ideal solution. What will be the mole fraction of B in the vapour phases ? p_(A)^(@) = 120 " torr ", p_(B)^(@) = 80 torr

Two liquid A & B form an ideal solution. What is the vapour pressure of solution containing 2 moles of A and 3 moles at B at 300K? [Given: At 300K, Vapour pr. Of pure liquid A ("P"_("A")^(@)) =100 torr, Vapour pr. Of pure liquid B ("P"_("B")^(@)) = 300 torr]

Two liquids A and B form an ideal solution. What is the vapour pressure of solution containing 2 moles of A and 3 moles of B at 300 K? [Given : At 300 K, vapour pressure of pure liquid A (p _A^0) = 100 torr and vapour pressure of pure liquid B (p _B^0) = 300 torr]

At 300K, the vapour pressure of an ideal solution containing 3 mole of A and 2 mole of B is 600 torr. At the same temperature, if 1.5 mole of A & 0.5 mole of C (non-volatile) are added to this solution the vapour pressure of solution increased by 30 torr. What is the value of "P"_("B')^(@) ?
