H2O is the molecular formula for water, also known chemically as dihydrogen monoxide. H is the elemental symbol of hydrogen, and O corresponds to oxygen. H with the subscript of 2 signifies the presence of 2 of its atoms per molecule. The number 12 before the formula indicates a quantity of 12 water molecules.
