The molality of a \( 10\% \) (v/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 \( \mathrm{Br_2} = 160 \, \mathrm{g\,mol^{-1}} \), 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 \( \mathrm{CCl_4} = 1.6 \, \mathrm{g\,cm^{-3}} \)).
