277321 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?

277322 At room temperature, a dilute solution of urea is prepared by dissolving $0.60 \mathrm{~g}$ of urea in $360 \mathrm{~g}$ of water. If the vapour pressure of pure water at this temperature is $35 \mathrm{~mm} \mathrm{Hg}$, lowering of vapour pressure will be (Molar mass of urea $=$ $60 \mathrm{~g} \mathrm{~mol}^{-1}$ )

277323 Acetic acid dimerizes when dissolved in benzene. As a result boiling point of the solution rises by $0.36^{\circ} \mathrm{C}$, when $100 \mathrm{~g}$ of benzene is mixed with " $\mathrm{X}$ " $\mathrm{g}$ of acetic acid. In this solution, if experimentally measured molecular weight of acetic acid is $\mathbf{1 1 7 . 8}$ and molar elevation constant of benzene is $2.57 \mathrm{~K} \mathrm{kgmol}^{-1}$, what is the weight \% and degree of dissociation (in \%) of acetic acid in benzene?
