formula

(for'myu-la) [L. formula, a register]
1. A rule prescribing ingredients and proportions for the preparation of a compound.
2. In chemistry, a symbolic expression of the constitution of a molecule. It consists of the symbols of its component elements, each denoting one atom, with subscripted numbers denoting the number of atoms present. Water, or H2O, consists of two molecules of the element hydrogen and one of oxygen. It may also be written HOH.

Collections of atoms that constitute a group by themselves (radical) are often separated by periods or parentheses. In this case, figures prefixed or appended to the parentheses, or prefixed to an expression contained within periods, apply to all the symbols embraced by the parentheses or periods. In all other cases, a figure prefixed to a symbolic expression for a molecule, such as a coefficient in an algebraic formula, is a multiplier of all the symbols following.
