(a,c) Most of the elements are found in nature as a mixture of isotopes which have different atomic masses. Therefore, the atomic mass of any element is the average of the atomic masses of isotopes of that element Example: Given that the abundance of isotopes and is 5%, 90% and 5% respectively, the atomic mass of is calculated as follows: Atomic mass of iron = |
