2.7 Kg of each of water and acetic acid are mixed, The freezing point of the solution will be $-\mathrm{x}^{\circ} \mathrm{C}$.
Consider the acetic acid does not dimerise in water, nor dissociates in water $\mathrm{x}=$ $\_\_\_\_$ (nearest integer)
[Given : Molar mass of water $=18 \mathrm{~g} \mathrm{~mol}^{-1}$, acetic $\operatorname{acid}=60 \mathrm{~g} \mathrm{~mol}^{-1}$ ]
${ }^{\mathrm{K}_f} \mathrm{H}_2 \mathrm{O}: 1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$
${ }^{\mathrm{K}_{\mathrm{f}}}$ acetic acid : $3.90 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$
freezing point : $\mathrm{H}_2 \mathrm{O}=273 \mathrm{~K}$, acetic acid $=290 \mathrm{~K}$ ]
