We’re being asked to calculate the  average current generated in the electrochemical cell if 50 g of Cu(s) are used up in a 24 hour period:

Cu(s) I Cu2+(aq) II Fe3+(aq) I Fe(s)

Cu2+ + 2e- → Cu              E°red = +0.22 V

Fe3+ + 3e- → Fe               E°red = -0.04 V

We’re going to calculate the average current generated using the following steps:

Step 1: Determine which cation (positively charged ion) will be plated out from the solution.
Step 2: Write the reaction.
Step 3: Calculate the average current generated.
