Jan 30, 2012 ... If you're given the mass of each isotope of an element, and the average atomic
mass, you can calculate the percent (%) abundance of each ...
In the other tutorial, the average atomic weight is the unknown value calculated.
In this tutorial, the unknown values calculated are the TWO percent abundances.
Percent abundance can be calculated by finding the percentage of an isotope
compared to another isotope of an element using its relative atomic mass. This is
Average atomic mass= ∑ (Mass of isotope × Percentage isotope abundance)If
the element Y has Y1, ...
