How to calculate isotopic mass

Web11 sep. 2024 · To calculate the relative atomic mass, A r, of chlorine: \[A_{r} = \frac{total~mass~of~atoms}{total~number~of~atoms} = \frac{(75 \times 35)+(25 \times … WebWe start by multiplying each isotopes’ mass by its abundance. This can be done in two ways. First, we can directly multiply the mass by the percent: 23.985 amu (78.70)= 1887.6 amu On the other hand, we can change the percent to a decimal out of one and then multiply by the mass. This can be done by dividing the percent by 100.
