P_A and P_B are the vapour pressure of pure liquid components. A and B, respectively of an ideal binary solution. If x_A represents the mole fraction of component A, the total pressure of the solution will be

100g of liquid A(molar mass 140"g mol"^(-1) ) was dissolved in 1000g of liquid B(molar mass 180"g mol"^(-1) ). The vapour pressure of pure liquid B was found to be 500 torr. Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is 475 torr.

Which of the following statements are correct (a) the boiling point of a solution is greater than pure solvent (b) the temperature where the vapour pressure of liquid equals to atmospheric pressure is called its boiling point (c) the vapour pressure of pure solvent is less than the vapour pressure of solution containing non volatile solute. (d) the temperature of liquid remained in the container after evaporation is more than before the evaparation

At 100^@C vapour pressure of heptane and octane are respectively 105.2 and 46.8 kPa. Calculate the vapour pressure of 60 grams of the mixture of two liquids, in which the mass of octane is 35g.

Assertion: The pressure exerted by the vapour of a liquid at equilibrium at a given temperature is called its vapour pressure. Reason: If a nonvolatile solute is added to a solvent to give a solution, the vapour pressure of the solution is found to be greater than the vapour pressure of the pure solvent.

Vapour pressure of pure liquids P and Q are 700 and 450 mm Hg respectively at 330K. What is the composition of the liquid mixture at 330 K, if the total vapour pressure is 600 mm Hg?
