This section provides a quick definition for what is a molecule formula.

What Is Molecule Formula? - A Molecule Formula is an expression of element symbols and numbers of atoms of same element types that bonded together to form the molecule. If the number of atoms of an element type is 1, it is omitted from the formula. If the number of atoms of an element type is greater than 1, it is expressed as a subscript following the element symbol.

Examples of molecule formulas:

Molecule formula for Dioxygen is O₂.
Molecule formula for Water is H₂O.
Molecule formula for Carbon Dioxide is CO₂.
Molecule formula for Salt is NaCl.
Molecule formula for Sugar is C₆H₁₂O₆.
