The sample problem below demonstrates how to calculate the atomic mass of chlorine.1. The atomic mass of an element is the weighted average of the atomic masses of the naturally occurring isotopes of that element. Why? We need to take into account the percent natural abundance of each isotope, in order to calculate the weighted average. \nonumber \]Ĭlearly the actual average atomic mass from the last column of the table is significantly lower.
