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 atm` pressure is `2^(@)C`. Assuming concentration of solute is much lower than the concentration of solvent, the vapour pressure (`mm` of `Hg`) of the solution is (take `K_(b)=0.76 K kg mol^(-1)`)
