Chemical Formula Description

The Phenylmethanesulfonamide molecule contains a total of 20 atom(s). There are 9 Hydrogen atom(s), 7 Carbon atom(s), 1 Nitrogen atom(s), 2 Oxygen atom(s) and 1 Sulfur atom(s). A chemical formula of Phenylmethanesulfonamide can therefore be written as:


The chemical formula of Phenylmethanesulfonamide shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.

The above chemical formula is the basis of stoichiometry in chemical equations, i.e., the calculation of relative quantities of reactants and products in chemical reactions. The law of conservation of mass dictates that the quantity of each element given in the chemical formula does not change in a chemical reaction. Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula.
