1.0M CuSO4 solution was electrolyzed for 28 minutes and 22 seconds using copper electrodes. The average current flowing through the cell over the time period was 0.622 A. The mass of the copper anode before electrolysis was 2.4852g and 2.1335g afterward. a) Calculate the number of moles of copper oxidized and moles of electrons that passed through the cell. b) Calculate the total charge (coulombs) that passed through the cell. c) How many electrons passed through the cell during the 28.0 minute and 22 second time period. d) From the data ,calculate Avogadro's number.
