Calculate the change in mass of the In electrode after the cell supplies 100 mA of current for 10 minutes. The balanced redox reaction is 2In+Cl2=2In+ + 2Cl-.
I understand the idea behind the question, I just don't know if I should use 1 mol In per 1 mol e- or 1 mol In per 2 mol e- when doing the calculations.

If your equation is right use 2 mol e. However, I'm somewhat surprised In doesn't go to In^3+.
