This is a more challenging problem using atomic mass. I show you haw to calculate the percentages of the isotopes of an element using the masses of the isotopes and the atomic mass from the periodic table.

OMG thank you! My chem. prof. went 900mph on this. Thanks for the simple breakdown!

Thanks for the video! Also, what calculator app are you using? And do you have any useful links for understanding mass spec, IR spec, NMR spec and H NMR?

What about calculating the isotopes of an unknown element? For example: Calculate the atomic weight (in amu) of an element (X) given the following data:

24X: 24.000 amu at 0.7870 fractional abundance
26X: 26.000 amu at 0.1017 fractional abundance
25X: 25.000 amu at 0.1113 fractional abundance
