How Do You Calculate Natural Abundance . The relative abundance of an isotope is the percentage of atoms with a specific atomic mass found in a naturally occurring sample of an element. To calculate the atomic mass of oxygen using the data in the above table, we must first. Natural abundance of the lead isotopes Download Table from www.researchgate.net Set up the relative abundance problem. How much of x is in y. To learn how to calculate atomic mass using percentage abundance and isotopic masses click here.
