Solutions Part 2

2.5g of a non-volatile, non-electrolyte is dissolved in 100g 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)=0.52K.kg‌mol−1,
1‌atm pressure =760‌mm of Hg, molar mass of water =18gmol−1]
