The average atomic mass of your mixture is 1.03 u.
The average atomic mass of H is the weighted average of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i. e., its % abundance).
Thus,
0.99 * 1.01 u = 0.998 u
0.002 * 2.01 u = 0.004 u
0.008 * 3.02 u = 0.024 u
TOTAL = 1.03 u
