Purification of chromium can be achieved by electrorefining chromium from an impure chromium anode onto a pure chromium cathode in an electrolytic cell. Calculate the amount of hours it will take to plate 18.5 kg of chromium onto the cathode if the current passed through the cell is held constant at 33.0 A. Assume the chromium in the electrolytic solution is present as Cr3 . (answer expressed in hours)
