1. Formula unit mass is calculated by adding the atomic masses of all atoms in a chemical formula. Multiply the atomic mass of each element by its subscript, then sum them for the total mass.

  2. Formula unit mass is the mass of one formula unit of a substance, expressed in atomic mass units (amu) or grams per mole (g/mol). It is determined by summing the atomic masses of all atoms in the chemical formula.

  3. Molecular mass is expressed in atomic mass units (amu) because it represents the sum of the masses of all atoms within a molecule relative to the unified atomic mass unit. This allows for convenient comparison and calculation of relative masses in chemistry.
