51.86% of all the isotopes of an element have a mass of 106.82 amu and 48.14% have a mass of 109.03 amu. What is the average mass of this element?

Average Mass = 107.88 amu

Explanation:

We can calculate the average mass of an element by mutlpying the mass of its isotopes by their respective relative abundance and then making a total sum. Meaning that for this case:

the answer is: they rebelled against saddam hussein’s rule.
