Taking chlorine as an example, you will find in most periodic tables that the mass number of chlorine is 35.5. Calculate the average atomic mass of lithium. To calculate the atomic mass of an element, we have to calculate how much each isotope contributes to the mass of the atom. On the other hand, the atomic mass is the number of protons and neutrons in a given atom. Now, do not forget that the atomic mass of an isotope is approximately equal to the number of protons and neutrons that isotope has in its nucleus. An average atomic mass is the weighted average of the atomic masses of the naturally occurring isotopes of an element. To calculate the average atomic weight, each exact atomic weight is multiplied by its percent abundance (expressed as a decimal).
