Atomic mass is the sum of the masses of the protons, neutrons, and electrons in an atom, or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don’t factor into the calculation. So, the atomic mass is.

Atomic mass is the total mass of protons and neutrons in an individual atom or isotope. Atomic weight is the average mass of all of the naturally-occurring isotopes of an element. Both atomic mass and atomic weight are represented using a unit called the atomic mass unit (​amu), which was defined using carbon’s most common isotope, carbon-12.
