Calculate the vapour pressure , if 0.083 mole of a non-volatile solute is present in 80 g of ethanol at `25^@C` , Vapour pressure of ethanol is 22.45 mm.

Calculate the vapour pressure of a solution containing 10gm of non-volatile solute in 80gm of ethanol of at 298K [The vapour pressure of pure ethanol at 298K is 22.45 mm and Molecular weight of solute is 120]

At 20^@C , the vapour pressure of diethyl ether is 442mm. When 6.4g. of a non-volatile solute is dissolved in 50g. of ether, the vapour pressure falls to 410mm. The Molecular weight of the solute is

What happens to the vapour pressure of a liquid when a non-volatile solute is dissolved in it ?

The vapour pressure of a solution containing non volatile solute is less than the vapour pressure of pure of solvent. Give reason.

Vapour pressure in mm Hg of 0.1 mole of urea in 180 g of water at 25^(@)C is (The vapour pressure of water at 25^(@) C is 24 mm Hg)

Calculate the vapour pressure of a solution containing 9g of glucose in 162g of water at 293K. The vapour pressure of water of 293K is 17.535mm Hg.

The vapour pressure of 4% solution of a non-volatile solute in water at 100^@C is 745 mm. What is the molecular weight of solute?

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.
