The simplest type of formula is the molecular formula, which also provides the least information about the molecule. What do Molecular Formulae look like ? Molecular formulae will be familiar to most students from the way they are used to representing simple chemical compounds in school-level inorganic chemistry.
A molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. (A subscript is used only when more than one atom of a given type is present.) Molecular formulas are also used as abbreviations for the names of compounds.
