The mass of ${\mathrm{Cl}}_2$ produced in the electrolysis of molten sodium chloride when 1A of current is passed for 10 min is 0.22 g.

Since $m=(Q/F)\left(M/\left|{\mathrm{v}}_{\mathrm{e}}\right|\right)$ for the oxidation of ${\mathrm{Cl}}^{-}$ we get

$m=\left(\frac{1\times 10\times 60\mathrm{C}}{96500\mathrm{C}{\mathrm{mol}}^{-1}}\right)\left(\frac{35.5{\mathrm{mol}}^{-1}}{1}\right)\simeq \frac{1}{5}\mathrm{g}.$
