The atomic number or nuclear charge number of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number or the number of protons found in the nucleus for every atom of that elem
Molecular mass is the sum of atomic mass, measured in amu.
The mass of one carbon atom is equal to the atomic mass unit (formerly abbreviated as 'amu,' but now spelled as 'u' – unified mass) according to the latest IUPAC recommendation.
