${\mathrm{AB}}_2$ is 10% dissociated in water to ${\text{A}}^{\text{2+}}{\text{\hspace{0.17em}and\hspace{0.17em}B}}^{-}$ the boiling point of a 10.0 molal aqueous solution of ${\mathrm{AB}}_2$  is ……….. .°C   (Round off to the Nearest Integer).

[ Given: Molal elevation constant of water ${\mathrm{K}}_{\mathrm{b}}=0.5 \mathrm{K} \mathrm{kg} {\mathrm{mol}}^{-1}$ and boiling point of pure water =100°C ]
