In а clаssrооm demоnstrаtion of a redox reaction, Professor Smith set up a voltaic cell with a copper metal anode and a silver metal cathode. The two electrodes were in contact with solutions of the corresponding metal ions, Cu2+ and Ag+. During the illuminating lecture on redox chemistry, the crystals of silver metal deposited on the silver electrode as the copper solution turned a darker blue. The added silver crystals had a mass of 2.68 g after 50 minutes of lecture. What was the average current, in amperes, that the cell produced? 1Faraday=96500 C
