The degree of dissociation of $\mathrm{Ca}{\left({\mathrm{NO}}_3\right)}_2$ in dilute aq. solution containing $7.0\mathrm{g}$ of salt per $100\mathrm{g}$ of water at $100^{\circ }\mathrm{C}$ is $70\%$. If vapour pressure of water at $100^{\circ }\mathrm{C}$ is $760\mathrm{mm}\mathrm{Hg}$. The vapour pressure of solution is
