Answer to Problem 56A

The average mass deals with the individual atomic mass of isotopes while the weighted average mass deals with the relative abundance of isotopes and their mass.

Explanation of Solution

Average mass is the arithmetic mean of each isotope's atomic masses.

The weighted average mass of the atoms in a naturally occurring sample of an element is the atomic mass.

The mass and relative abundance of isotopes as they appear in nature are both reflected in the weighted average mass.

The value of average mass differs from the weighted average mass.
