The mole is one of the most important concepts in chemistry, as it allows for quantitative calculation of amounts of substances that may take part in chemical reactions. Various formulas are used to calculate the amount of substance (in mol): n = m M, where n = number of mol and M = molar mass (g mol–1) n = L N
