The atomic mass of the elements would be calculated by multiplying each isotopes mass my the relative abundance and then adding the two results together. 75% (6) = 4.5 25% (8) = 2.0 4.5 + 2.0 = 6 ...
When measuring the atomic mass, scientists settle on using the average mass of the naturally occurring mixture of isotopes. Calculating the Average Atomic Mass Take a look at carbon: The natural abundance of carbon-12 and carbon-13 are 98.90 percent and 1.10 percent respectively.
