Expert Answer:

Atomic mass and mass of an atom is the same. The atomic mass is defined as the mass of an atom, which can only be one isotope at a time and is not an abundance-weighted average like atomic weight.

Relative atomic mass is a synonym for atomic weight and is defined as the weighted mean of the atomic masses of all the atoms of a chemical element found in a particular sample, weighted by isotopic abundance.
