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

When some amount of non-volatile solute is dissolved in a solvent to prepare a dilute solution, the vapour pressure of the solvent is lowered and it is directly proportional to the mole fraction of solvent in the solution . Relative lowering in vapour pressure is equal to mole fraction of solute . Elevation in boiling point of solvent is a collgative property like lowering in vaour pressure of solvent in solution , K_(b) i.e., molal elevation constant is calculated by the formula, K_(b)=DeltaT_(b)// molality and also by the expression, K_(b)=RT_(b)^(2)//1000l_(v) where T_(b) is boiling point of solvent and I_(v) is latent heat of vapourisation for 1 gm solvent . Abnormal elevation is boiling point =iX elevation in boiling point in ideal solution where i=van't Hoff factor Lowering in vapour pressure in an experiment was found to be x mm of Hg.

The vapour pressure of water at room temperature is 23.8 mm Hg. The vapour pressure of an aqueous solution of sucrose with mole fraction 0.1 is equal to :

When 25 g of a non-volatile solute is dissolved in 100g of water, the vapour pressure is lowered by 2.25 xx 10^(-1)mm . If the vapour pressure of water at 20^(@)C is mm, what is the molecular weight of the solute?

Vapour pressure of an aqueous solution is 2% less than that of the solvent. The molality of the solution is
