2.5 g of a non-volatile, non-electrolyte is dissolved in 100 g of water at 25°C. The solution showed a boiling point elevation by 2°C. Assuming the solute concentration in negligible with respect to the solvent concentration, the vapour pressure of the resulting aqueous solution is _______ mm of Hg (nearest integer)
[Given : Molal boiling point elevation constant of water (Kb) = 0.52 K. kg mol–1,
1 atm pressure = 760 mm of Hg, molar mass of water = 18 g mol–1]
