Why do we need to calculate the average atomic mass of isotopes of an element for computation?
(N/A) Elements exist in nature as a mixture of different isotopes,each with a specific relative abundance. Because these isotopes have different atomic masses,a single atomic mass value cannot represent the element accurately. Therefore,the average atomic mass is calculated by taking the weighted average of the masses of all naturally occurring isotopes based on their percentage abundance.
