Chemical Formula Description
The Sulfonfluorescein molecule contains a total of 38 atom(s). There are 12 Hydrogen atom(s), 19 Carbon atom(s), 6 Oxygen atom(s), and 1 Sulfur atom(s). A chemical formula of Sulfonfluorescein can therefore be written as:
C19H12O6S
The chemical formula of Sulfonfluorescein 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.
