WebFor example, the atomic mass of Lithium is 6.941 Da. On the basis of the abundance of isotopes, we can calculate the isotopic mass and average atomic mass of an element. The average mass of element E can be expressed as: m ( E) = ∑ n = 1 m ( I n) × p ( I n) For example, the mass and abundance of isotopes of Boron are given below.
