Chapter 19, Problem 64E

A quantity of electric charge brings about the deposition of 328 g Cu at a cathode during the electrolysis of a solution containing ${\text{Cu}}^{\text{2+}}\left(\text{aq}\right)$ . What volume of ${\text{H}}_2\left(g\right)$ , measured at $28.2°\text{C}$ and 763 mmHg, would be produced by this same quantity of electric charge in the reduction of ${\text{H}}^{\text{4}}\left(\text{aq}\right)$ at a cathode?
