An element has 2 isotopes: 6X at 7.59% and 7X at 92.41%.<br> What is the average atomic mass?
crimeas [40]

The average atomic mass is 6.92X

How do we compute the average atomic mass?

In a bid to  calculate the average atomic mass, we  multiply the fraction of each isotope by the mass number , then add them together.

This is more like weighted average, as shown below:

average atomic mass=(mass number of first isotope*fraction)+(mass number of second isotope*fraction)

average atomic mass=(6X*7.59%)+(7X*92.41%)

average atomic mass= 6.92X
