→Solid Lead nitrate is dissolved in $1\,litre$ of water. The solution was found to boil at $100.15^{\circ}\,C$. When $0.2\,mol$ of $NaCl$ is added to the resulting solution, it was observed that the solution froze at $-0.8^{\circ}\,C$. The solutbility product of $PbCl _2$ formed is $...........\times 10^{-6}$ at $298\,K$. (Nearest integer) Given : $K _{ b }=0.5\,K\,kg\,mol ^{-1}$ and $K _{ f }=1.8\,kg\,mol ^{-1}$. Assume molality to be equal to molarity in all cases.
