Concept Introduction:
In a molecule, the sum of atomic weights of atoms is said to be its formula mass in other words we can say that formula mass is the sum of atomic masses of atoms of elements present in a molecule which have the lowest whole number ratio of ions or atoms represented in an ionic or covalent compound respectively.
The mass of an atom in the atomic mass unit (amu) is said to be its atomic mass units. It is exactly equal to one-twelfth the mass of one carbon-12 atom.
