What is empirical formula?
The empirical formula of a compound in chemistry is the simplest whole number ratio of atoms in a compound. Two simple instances of this concept are the empirical formulas of sulphur monoxide (SO) and disulfur dioxide (S2O2). As a result, the empirical formulas for the sulphur and oxygen compounds sulphur monoxide and disulfur dioxide are the same. However, they do not share the same molecular formulas, which indicate the number of atoms in each molecule of a chemical compound.
An empirical formula does not show the order or number of atoms. It is typical for many macromolecules, including ionic compounds like calcium chloride and silicon dioxide (SiO2) (CaCl2).
