At $\displaystyle 35^{\circ} \mathrm{C}$, the vapour pressure of $\displaystyle \mathrm{CS}_2$ is $\displaystyle 512$ mm Hg and that of acetone is $\displaystyle 344$ mm Hg. A solution of $\displaystyle \mathrm{CS}_2$ in acetone has a total vapour pressure of $\displaystyle 600$ mm Hg . The false statement amongst the following is :
Official answer
(2)
a mixture of $\displaystyle 100 \mathrm{~mL} \mathrm{CS}_2$ and $\displaystyle 100$ mL acetone has a volume < $\displaystyle 200$ mL
