Vapour pressure of chloroform $\left(CHC{l}_3\right)$ and dichloromethane $\left(C{H}_{2}C{l}_2\right)$ at $25°C$ are 200 mmHg and 41.5 mmHg respectively. Vapour pressure of the solution was obtained by mixing 25.5 g of $\left(CHC{l}_3\right)$ and 40 g of $\left(C{H}_{2}C{l}_2\right)$ at the same temperature will be: (Molecular mass of $\left(CHC{l}_3\right)$ = 119.5 u and molecular mass of $\left(C{H}_{2}C{l}_2\right)$ = 85 u)
