Solutions

The vapour pressure of pure \(\mathrm{CHCl}_3\) and \(\mathrm{CH}_2 \mathrm{Cl}_2\) are 200 and \(41.5 \mathrm{~atm}\) respectively. The weight of \(\mathrm{CHCl}_3\) and \(\mathrm{CH}_2 \mathrm{Cl}_2\) are respectively \(11.9 \mathrm{~g}\) and \(17 \mathrm{~g}\). The vapour pressure of solution will be
