The result, a measurement of the Avogadro constant, can then be used to calculate the Planck constant, using precise measurements of other fundamental constants--including the Rydberg constant, which is related to the energy needed to ionize a hydrogen atom.
And since the Avogadro constant is linked to the Planck constant via a fixed physical relation, both can be determined in one fell swoop.
The mole, symbol mol, is the unit of amount of substance of a specified elementary entity, which may be an atom, molecule, ion, electron, any other particle or a specified group of such particles; its magnitude is set by fixing the numerical value of the Avogadro constant to be equal to exactly 6.
