Zinc metal reacts with hydrochloric acid to form hydrogen gas via the reaction

SOLVED: Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas according to the following equation:Zn(s) 2HCl(aq)  ZnClz(aq) Hz(g)The product gas, Hz; is collected over water at a temperature of 25 *C and a pressure of 742 mm Hg: If the wet Hz gas formed occupies a volume of 6.21 L; the number of moles of Zn reacted was mol. The vapor pressure of water is 23.8 mm Hg at 25 PC.
