If M is molecular of solvent, K_(b) is molal elevation constant, T_(b) is its boiling point, P^(@) is its vapour pressure at temperature T and P_(s) is vapour pressure of its solution having a non-volatile solute at T K, then

Vapour pressure of a solvent is the pressure exterted by vapour when they are in equilibrium with its solvent at that temperature. The vapour pressure of solvent is dependent of nature of solvent, temperature, addition of non-volatile solute as well as nature of solute to dissociate or associate. The vapour pressure of a mixture obtained by mixing two valatile liquids is given by P_(M) = P_(A)^(@).X_(A)+P_(B)^(@).X_(B) where P_(A)^(@) and P_(B)^(@) are vapour pressures of pure components A and B and X_(A), X_(B) are their mole fractions in mixture. For solute-solvent system, the relatio becomes P_(M) = P_(A)^(@).X_(A) where B is non-volatile solute. If M is mol.wt. of solvent, K_(b) is molal elevation constant and t_(b) is its boiling point, P^(@) is its vapour pressure ta temperature T and P_(S) is vapour pressure of non-volatile solute in it at T K , then:

How is the vapour pressure of a solvent affected when a non volatile solute is dissolved in it?

The relative lowering of vapour pressure of an aqueous solution containing a non-volatile solute, is 0.0125. The molality of the solution is
