The natural percent
Explanation of Solution
The weighted average mass of the atoms in a naturally occurring sample of an element is the atomic mass.
Atoms that have various numbers of neutrons and different masses but the same number of protons are called isotopes.
The formula to calculate the atomic mass is given as:
To calculate the atomic mass, the data of the natural percent abundance of the isotopes of the element should be known.
