Q56. 2.5 g of a non-volatile, non-electrolyte is dissolved in 100 g of water at $25 ^ { \circ } \mathrm { C }$. The solution showed a boiling point elevation by $2 ^ { \circ } \mathrm { C }$. Assuming the solute concentration is negligible with respect to the solvent concentration, the vapor pressure of the resulting aqueous solution is $\quad \mathrm { mm }$ of Hg (nearest integer) [Given : Molal boiling point elevation constant of water $\left( \mathrm { K } _ { \mathrm { b } } \right) = 0.52 \mathrm {~K} . \mathrm { kgmol } ^ { - 1 } , 1 \mathrm {~atm}$ pressure $= 760 \mathrm {~mm}$ of Hg , molar mass of water $= 18 \mathrm {~g} \mathrm {~mol} ^ { - 1 }$ ]
