Answer 1

• the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
• The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, atomic mass is often expressed in the non-SI unit dalton – equivalently, unified atomic mass unit. 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state.
