The information needed to calculate the average atomic mass of an element includes the relative abundance of its isotopes.
To calculate the average atomic mass of an element, you need the relative abundance of its isotopes. The relative abundance refers to the percentage or proportion of each isotope present in a sample or in nature.
To determine the average atomic mass, you must multiply the mass of each isotope by its relative abundance, and then sum these values. The mass of each isotope can be found on the periodic table, usually listed as the atomic mass or atomic weight. Once you have the sum, you divide it by 100 to obtain the average atomic mass.
It is important to note that the charge on each isotope and the total amount of the element in the sample or in nature are not directly required for calculating the average atomic mass.
