Atomic mass, as mentioned above, is the mass of an atom while mass number is the number of nucleons (protons and neutrons) in an atom. Mass number is always a whole number while atomic mass is not (except in the case of carbon-12 when expressed in u. The ratio of atomic mass to mass number is always closed to one. This is shown in the table below.

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article.

EEE460-Handout Dec. 2014 K. E. Holbert ATOMIC NUMBER DENSITY Number of Atoms (n) and Number Density (N) The number of atoms or molecules (n) in a mass (m) of a pure material having atomic or molecular weight (M) is easily computed from the following equation using Avogadro's number (NA = 6.022×1023 atoms or molecules per gram-mole):

The atomic mass number of the isotope of hydrogen called protium is 1, while the atomic mass number of the isotope called deuterium is 2, yet the atomic mass is listed as 1.008. This is because natural elements are a mixture of isotopes.
