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 .

Vapour pressure of pure water at 298 K is 23.8 mm Hg. 50g urea (NH_(2)CONH_(2)) is dissolved in 850 g of water. Calculate the vapour pressure of water for this solution and its relative lowering. Consider Raoult's law and formula for relative lowering in vapour pressure, (P_(A)^(0)-P_(s))/(P_(A)^(0))=(n_(B))/(n_(A))=(W_(B))/(M_(B))xx(M_(A))/(W_(A)) Where, (P_(A)^(0)-P_(s))/(P_(A)^(0)) is called relative lowering in vapour pressure.
