how to calculate n correctly

I know that n in the equation deltaG^o=-nFE^o represents the number of moles of electrons transferred but was still confused on how to go about finding said number. Is there a specific calculation to find it or is it simply counting the number of electrons being transferred from one side to the other?

The number of electrons that you account for are the equal number of electrons transferring within each of the oxidation and reduction half reaction equations.

You can also balance the reactions by using the oxidation and reduction half reactions. Find the number of electrons that are cancelled out and that will be n.

For n, the moles of e-, does it have a unit, or is it just the number. For example, in deltaG=-nFE, if F is C/mol and E is J/C, is the n units mol so that delta G is J or is does the n have no units so that delta G =J/mol?

n is in moles so delta G is in J
