Multiple Choice

In a classroom demonstration 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, Cu^2 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 50.0 minutes of lecture. What was the average current that the cell produced?

A) 0.799 A
B) 2.40 A
