$\displaystyle 25$ mL of an aqueous solution of KCl was found to require $\displaystyle 20$ mL of $\displaystyle 1$ M $\displaystyle \mathrm{AgNO}_3$ solution when titrated using $\displaystyle \mathrm{K}_2 \mathrm{CrO}_4$ as an indicator. What is the depression in freezing point of KCl solution of the given concentration? $\displaystyle \_\_\_\_$ (Nearest integer). (Given: $\displaystyle \mathrm{K}_{\mathrm{f}}=2.0 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$ ) Assume $\displaystyle 1$) $\displaystyle 100 \%$ ionization and $\displaystyle 2$) density of the aqueous solution as $\displaystyle 1 \mathrm{~g} \mathrm{~mL}^{-1}$
