In chemistry, a molecular formula expresses the types and numbers of atoms present in a molecule or chemical, whereby subscripts are used to indicate the number of atoms present in the chemical entity. [1] The molecular formula for water, H20, for instance, means that there are two hydrogen atoms and one oxygen atom in one molecule of water.
