$A{B}_2$ 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 $A{B}_2$ is ……….. ${ }^{°}C.$ (Round off to the Nearest Integer). [Given: Molal elevation constant of water $K_b=0.5Kkgmo{l}^{-1}$ boiling point of pure water = ${100}^{°}C$
