What is atomic mass, for instance?

A mass corresponding to one-twelfth of an atom of carbon-12 is referred to as an atomic mass unit. Any isotope of any element's mass is represented in proportion to the standard carbon-12. For instance, the mass of one helium-4 atom is 4.0026 amu. Sulfur-32 atoms have a mass of 31.972 amu.

How is the definition of atomic mass determined?

The average mass of an element's atoms expressed in atomic mass units is the term "atomic mass" for an element (amu, also known as daltons, D). The mass of each isotope of that element is multiplied by its abundance to produce the atomic mass, which is a weighted average of all its isotopes.
