What is the Atomic Mass of Elements?

Atomic Mass of Elements

The atomic mass of an .

The atomic mass of an element can be calculated by multiplying the mass of each isotope by its relative abundance and then adding the results together. For example, the atomic mass of chlorine is 35.45 amu. This is calculated by multiplying the mass of chlorine-35 (34.96885 amu) by its relative abundance (75.77%) and then adding the mass of chlorine-37 (36.96590 amu) by its relative abundance (24.23%).
