Calculate the vapour pressure of aqueous 0.1 m glucose solution at 300 K temperature, the vapour pressure of water is 0.03 bar at 300 K temperature.

An ideal solution contains two volatile liquid A $$(p^{0}$$=100 torr) and B $$\ (P^{0}$$=200 torr). If the liquid mixture contains 1 mole of A and 4 mole of B then the total vapour pressure of the mixture obtained by condensing the vapour above this solution in a beaker is

$$5.0\ L$$ water placed in a closed room of volume $$2.5\times 10^{4}L$$ having temperature $$300\ K$$. If vapour pressure of water is $$27.0\ mm$$ and density is $$0.990\ g/cm^{3}$$ at this temperature, how much water is left in liquid state?  

Two liquids A and B have $${P_A}^0:{P_B}^0$$ = 1:3 at a certain temperature. If the mole fraction ratio  $${x_A}:{x_B} = $$ 1:3, the mole fraction of A in vapour in equilibrium with the solution at the given temperature is -
