A generic element, G, is composed of two isotopes, 132G and 128G. 132G has a natural abundance of 90% and an isotopic mass of 131.90 amu, and 128G has a natural abundance of 10% and an isotopic mass of 127.90 amu. What is the average atomic mass of this element?
Answers: 3
![A=\sum[(131.90\times 0.9)+(127.90\times 0.1)]=131.5amu](/tpl/images/0512/2891/2177c.png)
