A bourbon distillery treats its discharge water (that remains behind after the whisky distills off) electrochemically to remove copper by plating it out on an electrode. After 42 days of continuous operation the electrode was replaced. It was weighed before sending it off to a copper recycling service and was found to have recovered \(450 \mathrm{~g}\) of copper. Calculate the average current during its use assuming that \(100 \%\) of the current was used in the reduction of \(\mathrm{Cu}^{2+}\) to \(\mathrm{Cu}\) metal.
