Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas according to the following
equation:
Zn(s) + 2HCI(aq) ZnCl2(aq) + H2(g)
The product gas, H2, is collected over water at a temperature of 25 °C and a pressure of 754 mm Hg. If the
wet H2 gas formed occupies a volume of 6.46 L, the number of moles of Zn reacted was
mol.
The vapor pressure of water is 23.8 mm Hg at 25 °C.
