Some Basic Concepts Of Chemistry

The molality of a \(10 \%(\mathrm{v} / \mathrm{v})\) solution of di-bromine solution in \(\mathrm{CCl}_{4}\) (carbon tetrachloride) is '\(x\)'. \(x=\) ____________ \(\times 10^{-2} ~\mathrm{M}\). (Nearest integer)

[Given : molar mass of \(\mathrm{Br}_{2}=160 \mathrm{~g} \mathrm{~mol}^{-1}\)

atomic mass of \(\mathrm{C}=12 \mathrm{~g} \mathrm{~mol}^{-1}\)

atomic mass of \(\mathrm{Cl}=35.5 \mathrm{~g} \mathrm{~mol}^{-1}\)

density of dibromine \(=3.2 \mathrm{~g} \mathrm{~cm}^{-3}\)

density of \(\mathrm{CCl}_{4}=1.6 \mathrm{~g} \mathrm{~cm}^{-3}\)]
