Joule per mole
From Wikipedia, the free encyclopedia
The joule per mole (symbol: J·mol-1) is an SI derived unit of energy per amount of material. Energy is measured in joules, and the amount of material is measured in moles.
Physical quantities measured in J·mol-1 include:
When used to measure ionization energy, one can convert to electronvolts using the fact that
1 V = 1 J/coulomb = F J/mole of electrons = (96485.38 ± 0.02) J/mole of electrons
where F is Faraday's constant.
