Joe makes up a aqueous solution of a copper salt from some ore samples he has found in Contact, NV. He places a rod of pure copper into the solution making a cathode and uses a graphite rod as an anode. By electrolyzing the solution from a power supplu with a current of 1.50 Amperes he plates on 1.375 grams of copper onto the metal cathode. From this information determine how long a time the plating operation ran.
