WebThe percentage of abundance and isotopic mass is used to calculate the average isotopic mass. For example, two isotopes of Nitrogen are N-14 and N-15 and the average isotopic mass of Nitrogen is 14.007. The percentage abundance of both isotopes can be calculated as given below. (14.003074) (x) + (15.000108) (1 – x) = 14.007. Web1st step. All steps. Final answer. Step 1/1. The atomic mass of an element is the weighted average of the masses of all its isotopes, taking into account their relative abundance. Therefore, we can calculate the atomic mass of antimony as follows: Atomic mass = (isotope 1 mass x abundance of isotope 1) + (isotope 2 mass x abundance of isotope 2)
