Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas according to the following equation: Zn(s) + 2HCl(aq) ZnCl2(aq) + H2(g) The product gas, H2, is collected over water at a temperature of 25 C and a pressure of 755 mm Hg. If the wet H2 gas formed occupies a volume of 9.94 L, what is the number of mols of Zn reacted? The vapor pressure of water is 23.8 mm Hg at 25 oC.
