I'm a little confused on how to find the mass of zinc consumed from the data:
Mass of zinc produced: .745g
Mass of Zinc electrode before 7.705g
Mass of Zinc electrode after 8.450g
Length of time cell ran: 4.00 mins.
Also have to calculate the number of moles of electrons that passed through the cell during the electrolysis based off the amount of zinc produced on the iron nail. Would I need to use the molar mass of zinc or iron to calculate this.
