In order to know their number, a unit, mole is defined. Mole is the unit which
represents 6-023 x 1023 particles. The number 6-023 x 1023 is called
Avogadro's number, (N0). • The term amu (atomic mass unit) is used in place of
unified mass ...

Therefore, ca. 1920, Aston established the “physics mass scale” by declaring the
exact mass of the most abundant stable isotope of oxygen, 16O, to be 16. This
meant that there were now two different definitions for the atomic mass unit (amu)
.

1.4.1 Atomic Mass, Weight, Standard Weight and Atomic Mass Unit The atomic
mass∗∗ is the rest mass of an atom in its ground state. The commonly used unit
is the unified atomic mass unit (indicated by the symbol u, see Appendix A.2).
