The chemical formulae allow us to represent the chemical compounds in the form of symbols, brackets, signs of plus and minus, etc. One of the ways by which the chemical compounds and molecules are represented is an empirical formula.
The empirical formula is defined as the simplest ratio of the atoms that are present in the chemical compound. The arrangement of the atoms and their total number cannot be exhibited through the empirical formula.
Examples of Empirical Formula:
The molecular formula of some compounds can be written in a simplified form such as that of glucose, C6H12O6 as CH2O, sulfur dioxide, S2O2 as SO, etc. but there are many compounds whose molecular formula cannot be changed into an empirical formula like CO2, C12H22O11, etc.
