Title: Calculating the abundance of three isotopes with three unknown abundances
Post by: theslaight on October 07, 2020, 10:34:38 PM

Is it possible to calculate the abundances of three isotopes when you only know the average atomic mass and masses?   If you already know one of the abundances, you can represent the missing ones as (X) and (1-X) but I am at a complete loss at how to do it if all three abundances are missing.  Can anyone help?
