Formula Mass Unit. For polymer compounds, formula unit mass is the mass of a repeating unit. There are other ways to calculate the mass of an object, but these three formulae are the most.
The molecular mass (m) is the mass of a given molecule:
Molecular mass and formula unit mass an atom contains three types of particles i.e. The formula mass is the sum of all of average atomic masses of all atoms in the molecule, formula unit, or ion. It is calculated using the unit amu (atomic mass units). Define the amount unit mole and the related quantity avogadro's number explain the relation between mass, moles.
