**Zinc and Hydrochloric Acid Reaction** Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas according to the following equation: \[ \text{Zn(s) + 2HCl(aq)} \rightarrow \text{ZnCl}_2\text{(aq) + H}_2\text{(g)} \] The product gas, \( \text{H}_2 \), is collected over water at a temperature of 25 °C and a pressure of 754 mm Hg. If the wet \( \text{H}_2 \) gas formed occupies a volume of 8.94 L, the number of moles of Zn reacted was \(\_\_\_\_\_\) mol. The vapor pressure of water is 23.8 mm Hg at 25 °C.
