Molecular Formula vs Empirical Formula: What's the Key Difference? - postfix
📅 May 22, 2026👤 admin
A molecular formula represents the exact number and types of atoms present in a molecule, while an empirical formula represents the simplest whole-number ratio of atoms in a molecule. To illustrate the difference, consider a molecule of glucose (C6H12O6). Its molecular formula shows the exact number of carbon, hydrogen, and oxygen atoms, while its empirical formula (CH2O) represents the simplest whole-number ratio of atoms in the molecule.
