Calculate average atomic mass of an element
WebAr-40 is 99.6% of Ar and it weighs 39.96 amu and so on. So the atomic mass of Ar is 0.99639.96 + 0.0006337.96 + 0.00337*35.97 = 39.957. I divided the percentages by 100 to get fractions and then each mass contributes to the atomic mass according to its fraction -- weighted average.
