For a dilute solution containing 2.5 g of a non-volatile non-electrolyte solute in $100 g$ of water, the elevation in boiling point at $1 a t m$ pressure is $2 ℃$ . Assuming that the concentration of solute is much lower than the concentration of solvent, the vapour pressure $(in mm of Hg)$ of the solution is:

[Take : $K_{b} = 0.76 K k g m o l^{- 1}$ ]
