A mole is an amount of matter measured in [kg] .
The Avogadro's number can only be a dimensionless number, [1] .
The Avogadro's constant is the Avogadro's number (of "pieces" or
"objects") per mol, [1 / mol].

A chemist has to work and is always working in mole; as his
balance can only measure a mass, the calculation mole <-> mass
is always mandatory.

Why did I put this "mole" in the post scriptum?

Because there is a tendency on this list to be extremely
confused and to compare what is not comparable (eg. comparaison
of mole and Python large number, number and radian, byte and
unicode transformation unit).
