For a dilute solution containing \( 2.5 \mathrm{~g} \) of a non-volatile nonelectrolyte solute in \( 100 \mathrm{~g} \) of water, the elevation in boling point at \( 1 \mathrm{~atm} \) pressure is \( 2^{\circ} \mathrm{C} \). Assuming concentration of solute is much lower than the concentration of solvent, the vapour pressure (mm of \( \mathrm{Hg} \) ) of the solution is (take \( \mathrm{K}_{\mathrm{b}}=0.76 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1} \) )
