Quantitative analysis of an organic compound (X) shows following % composition.
C : $\displaystyle 14.5$ %
Cl : $\displaystyle 64.46$%
H : $\displaystyle 1.8$ %
(Empirical formula mass of the compound $\displaystyle (\mathrm{X})$ is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-1}$
(Given molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$ of $\displaystyle \mathrm{C}: 12, \mathrm{H}: 1, \mathrm{O}: 16, \mathrm{Cl}: 35.5$ )
