    the atomic mass of the element

    Explanation:

    By taking the weighted averages of the different isotopes of an element, one can calculate the atomic mass of the element.

    Using the process of mass spectrometry, one can simply determine the proportion/percentage/fraction by which each of the isotopes of an element occurs in nature. The proportion is called the geonormal abundance. We can then derive the atomic mass of an element which is the average mass of all the isotopes from this method.

    RAM = ∑mₓαₓ

    where mₓ is the mass of isotope x

    αₓ is the abundance of isotope x
