Chlorine is prepared in the laboratory by treating manganese dioxide ($MnO_2$) with aqueous hydrochloric acid according to the reaction - $4HCl_{(aq)} + MnO_{2(s)} \longrightarrow 2H_2O_{(l)} + MnCl_{2(aq)} + Cl_{2(g)}$
How many grams of HCl react with 5.0 g of manganese dioxide? (Atomic mass of Mn = 55u, O = 16u, H = 1u, Cl = 35.5u)
