What is the concentration of ${\mathrm{NO}}_3^{-}\mathrm{ion}$ when equal volumes of $0.1\mathrm{M} {\mathrm{AgNO}}_3 \mathrm{and} 0.1\mathrm{M} \mathrm{NaCI}$ are mixed together?

Vapour phase diagram for a solution is given below if dotted line represents deviation

Correct observation for this solution

A mixture of two liquids$\mathrm{A}$and$\mathrm{B}$ having boiling point of $\mathrm{A}$ is $70°\mathrm{C}$, and boiling point of $\mathrm{B}$ is $100°\mathrm{C}$, distills at $101.2°\mathrm{C}$ as single liquid, hence this mixture is
