(2.7 $\mathrm{~kg}$) of each of water and acetic acid are mixed. The freezing point of the solution will be (-x^{{}^{\circ}} $\mathrm{C}$). Consider the acetic acid does not dimerise in water, nor dissociates in water. $x=$ ______ (nearest integer) [Given: Molar mass of water (=18 $\mathrm{~g} \mathrm{~mol}^{-1}$), acetic acid (=60 $\mathrm{~g} \mathrm{~mol}^{-1}$) (\mathrm{K}_{\mathrm{f}} \mathrm{H}}_{2}\mathrm{O}$: 1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}) (\mathrm{K}_{\mathrm{f}}) acetic acid: (3.90 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}) freezing point: (\mathrm{H}$}_{2} $\mathrm{O}=$273 $\mathrm{~K}$), acetic acid (=290 $\mathrm{~K}$)]
