### non ideal gases

is n the amount of electrons transferred in the redox equation?

Yes, n is the amount of electrons transferred. When you add the half reactions to get the total reactions these number of electrons should cancel out

yes you obtain n by calculating the number of moles of electrons transferred.

Yes, n is the number of moles of electrons transferred in the redox reaction. After writing the two half-reactions, make sure they have an equal number of electrons being transferred, so that they cancel out when you add the half-reactions back together. Multiply the reactants and products in a reaction by the same number to do so.

yes, and not moles in the way we used to think of it, which is something that really confused me at first

yes, n is referring to the number of electrons transferred in the redox reactions involved at the anode and cathode.

When finding n though, make sure you don't accidentally double the value. You only need to count the electrons on one side of the redox reaction, as they are being transferred. So if 2 electrons are being transferred from Fe to Cl for example, make sure you don't count 4 from the 2 being transferred and the 2 being accepted.
