The formula unit mass is the sum of the atomic masses of all the elements present in the corresponding compound.
The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. ... 75.53 of these atoms each have a mass of 35 atomic mass units (AMU), and 24.47 atoms each have a mass of 37 AMU.
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons
the mass of a molecule that is equal to the sum of the masses of all the atoms contained in the molecule.
Isobars are atoms or nuclides of separate chemical elements having the same number of nucleons
