A solution containing $\displaystyle 2.5 \times 10^{-3} \mathrm{~kg}$ of a solute dissolved in $\displaystyle 75 \times 10^{-3} \mathrm{~kg}$ of water boils at $\displaystyle 373.535$ K . The molar mass of the solute is \_\_\_\_ $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$. [nearest integer] (Given : $\displaystyle \mathrm{K}_{\mathrm{b}}\left(\mathrm{H}_2 \mathrm{O}\right)=0.52 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$ and boiling point of water = $\displaystyle 373.15$ K)
