Formula Mass
Formula mass is the sum of the atomic weight of all atoms in a molecule or compound. It can be expressed in atomic mass unit. It is used to obtain the mass of either a single molecule or a given number of molecules. Understanding the formula mass for atomic mass is important to write balanced chemical equations, determine the molar mass, and do stoichiometry calculations. This article explains the formula mass, its calculation, and its applications with examples.
