Copper deposited from electrons
During electrolysis in a university-style problem set, \(0.02\,\text{mol}\) of electrons pass through \(Cu^{2+}+2e^-\rightarrow Cu\). Calculate moles of copper deposited. Use the labelled diagram, graph, equation, or table before answering. Enter the answer and choose the interpretation that matches the HL chemistry evidence.
