### DG = -nFE

Can someone please explain which compound's number of moles we put when using this equation?

I believe n refers to electrons transferred. Basically, you find the number of electrons in each balanced half-reaction and if they match, that is n. If they don't, you use the lowest common multiple as n.

n refers to the number of moles of electrons (which should be the same in the oxidation and reduction half reactions if they're balanced)

I think you just have to balance the equations.
