25 mL of an aqueous solution of KCl was found to require 20 mL of 1 M $${\mathrm{AgNO}}_3$$ solution when titrated using $${\mathrm{K}}_2{\mathrm{CrO}}_4$$ as an indicator. What is the depression in freezing point of KCl solution of the given concentration? _________ (Nearest integer).

(Given : $${\mathrm{K}}_{\mathrm{f}}=2.0\mathrm{K}\mathrm{kg}{\mathrm{mol}}^{-1}$$)

Assume 1) 100% ionization and 2) density of the aqueous solution as 1 g mL$${}^{-1}$$
