Avogadro's law: equal volumes of gases contain equal numbers of molecules Avogadro's law Avogadro's law states that equal volumes of gases, at the same temperature and pressure, contain the same number of molecules. It underpins the mole concept and gas stoichiometry.
Chemical stability Chemical stability is a substance's tendency to resist reacting or breaking down. It depends on composition, bonding, and conditions such as heat, light, and air.
