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.
To do these problems you need some information: the exact atomic weight for
each naturally-occuring stable isotope and its percent abundance. These values

I've seen this very question from an AQA paper and no percentage abundance of
either of the isotopes was given. This can be solved through ...
In this case, you want to find the percentage of the lighter isotope, so the "x" is
associated with 106.90509. Since the sum of the isotopic abundance
