Metal plating is done by passing current through a metal solution. For example, an item can become gold plated by attaching the item to a power source and submerging it into a Au^3+ solution. The item itself serves as the cathode, at which the Au^3+ ions are reduced to Au(s). A piece of solid gold is used as the anode and is also connected to the power source, thus completing the circuit.

What mass of gold is produced when 15.0A of current are passed through a gold solution for 15.0min?
