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 752.0 mm Hg. If the wet H₂ gas formed occupies a volume of 7.62 L, the number of grams of H₂ formed is I g. The vapor pressure of water is 23.8 mm Hg at 25 °C.
