Chemistry - Liquid Solution Question with Solution | TestHub

$2.5\mathrm{g}$ of a non-volatile, non-electrolyte is dissolved in $100\mathrm{g}$ 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 $\mathrm{mm}$ of $\mathrm{Hg}$ (nearest integer) [Given : Molal boiling point elevation constant of water $\left({\mathrm{K}}_{\mathrm{b}}\right)=0.52\mathrm{K}.\mathrm{kg}{\mathrm{mol}}^{-1}$, $1\mathrm{atm}$ pressure $=760\mathrm{mm}$ of $\mathrm{Hg}$, molar mass of water $=18\mathrm{g}{\mathrm{mol}}^{-1}$]
