The average atomic weight is calculated by adding up the products of the percentage abundance and atomic weight. In this item, we have the equation,
A = (0.412)(21.016 amu) + (0.5012)(21.942 amu) + (0.0868)(23.974 amu)
Simplifying the operation will give us the answer of 21.74 amu.
<em>Answer: 21.74 amu</em>
