Number of electrons lost or gained by
one rmlecule of oxidant or reductant
If oxidant, reductant are compounds, use molar mass of
oxidant or reductant compounds.
Ifoxidant, reductant are elements, use atomic mass ofoxidant
or reductant elements.
For detail see chapter oxidation-reduction.
In case of redox change, always use the eq. (12), and do
not use any other formulae.
The denominator used in equation (12) represents 'n' factor
of oxidant or reductant as the case may be
