At room temperature, a dilute solution of urea is prepared by dissolving $\displaystyle 0.60$ g of urea in $\displaystyle 360$ g of water. If the vapour pressure of pure water at this temperature is $\displaystyle 35$ mmHg , lowering of vapour pressure will be : (molar mass of urea $\displaystyle =60 \mathrm{~g} \mathrm{~mol}^{-1}$ )
Official answer
(3)
0.$\displaystyle 017$ mmHg
