Aqueous HCl reacts with $\displaystyle \mathrm{MnO}_2(\mathrm{~s})$ to form $\displaystyle \mathrm{MnCl}_2(\mathrm{aq}), \mathrm{Cl}_2(\mathrm{~g})$ and $\displaystyle \mathrm{H}_2 \mathrm{O}(l)$. What is the weight (in g) of $\displaystyle \mathrm{Cl}_2$ liberated when $\displaystyle 8.7$ g of $\displaystyle \mathrm{MnO}_2(\mathrm{~s})$ is reacted with excess aqueous HCl solution? (Given Molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1} \mathrm{Mn}=55, \mathrm{Cl}=35.5, \mathrm{O}=16, \mathrm{H}=1$ )
