Concept introduction:
The average mass of an atom of element depends on the atomic masses of its isotopes and their natural abundances.
For example, if an atom X has two isotopes A and B respectively. The average atomic mass of atom X can be calculated as follows:
Here, MA is mass of isotope A, MB is mass of isotope B, %A is percent
