Question

I need help with some lab questions for the Electrolysis and Electroplating Lab:

1.) Find the

actual mass of metal plated out for Cu/Cu cell and Zn/Zn cell.

2.) Find the Coulomb passed during the reaction for Cu/Cu cell and Zn/Zn cell.

3.) Find the theoretical mass of metal plated out for Cu/Cu cell and Zn/Zn cell.
