Answer:
The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance
Explanation:
To determine the average atomic mass, we require abundance of every isotope in the nature.
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
