Hello, to find the answer in this question, I am assuming it is trying to ask for the atomic mass
Usually we have the relative abundance in a percentage form, but it looks as if these have already been converted or divided by 100
So first what we do since we have the isotopes and their mass numbers, we multiply each of these with their given abundances.
(24 x 0.79) + (25 x 0.10) + (26 x 0.11)
= 24.32
The gram atomic mass of magnesium is 24.32 amu
