Calculate formula masses for covalent and ionic compounds. In this chapter we will study about center of mass of system of particles, motion of center of mass and about collisions. Units, difference between molecular mass and formula mass, examples and calculations, to determined formula mass of sodium the formula mass is often confused with the molar mass or the molecular mass, but it differs from both.

It is calculated using the unit amu (atomic mass units).

Formula mass is the average mass of a molecule calculated as the sum of the individual atomic masses. The relative formula mass of a substance is the sum of the relative atomic masses of the elements present in a formula unit. Mole, atomic mass unit (amu), formula mass, gram formula mass, empirical formula, molecular formula. The subscript number after the brackets multiplies whatever is in the brackets (a bit like in maths).
