What are the differences between atomic and relative atomic mass?

The differences between atomic mass and relative atomic mass are as follows:-

Atomic MassRelative Atomic Mass
1. The Atomic Mass is basically the mass of an atom.
1. Relative Atomic Mass is an average of values for many atoms in a given sample of a chemical element.

2. Atomic mass is an absolute mass.

It is expressed in dalton (symbol: Da, or u) where 1 dalton is defined as ​1⁄12 of the mass of a single carbon-12 atom, at rest.

2. Relative isotopic mass is a dimensionless number with no units.
