WebSep 1, 2024 · What is a mole in chemistry BBC Bitesize? The mole is the unit for amount of substance. It is abbreviated to mol. 1 mol is the amount of substance that contains the same number of particles as there are atoms in 12.0 g of carbon-12. Since atoms are so very small and have very little mass , the number of atoms in 12.0 g of carbon-12 is huge. WebThe units for concentration can also be shown as mol dm 3 or M (for 'molar'), but these mean the same as mol dm 3.
