Q. The molality of a $10\%(\mathrm{v/V})$ solution of di-bromine solution in $\mathrm{CCl_4}$ (carbon tetrachloride) is $\mathrm{x}$ '. $\mathrm{x}=$ _____ $\times10^{-2}\mathrm{M}$. (Nearest integer) [Given : molar mass of $\mathrm{Br_2}=160\ \mathrm{g\ mol^{-1}}$ atomic mass of $\mathrm{C}=12\ \mathrm{g\ mol^{-1}}$ atomic mass of $\mathrm{Cl}=35.5\ \mathrm{g\ mol^{-1}}$ density of dibromine $=3.2\ \mathrm{g\ cm^{-3}}$ density of $\mathrm{CCl_4}=1.6\ \mathrm{g\ cm^{-3}}$]
