Coulomb Unit

Can somebody briefly explain once more why we don't use the units "J/mol" of electrons to represent work, rather we use "J/C"?

Re: Coulomb Unit

J/C is used to indicate the potential difference because a Columb is defined as the amount of charge in 6.24x10^18 electrons. Therefore, the potential difference is defined as the energy transferred between two compounds per Coulomb of charge.

Re: Coulomb Unit

One coulomb is the amount of electrical charge in 6.24*10^18 electrons. Coulomb is just a convenient unit that allows for the volt unit to be equal to 1J/C.
