25 mL of an aqueous solution of KCl was found to require 20 mL of 1 M \(\mathrm{AgNO_3}\) solution when titrated using \(\mathrm{K_2CrO_4}\) as an indicator. What is the depression in freezing point of KCl solution of the given concentration? _________ (Nearest integer).

(Given : \(\mathrm{K_f=2.0~K~kg~mol^{-1}}\))

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