*Mole* | *documentation* SI AmountOfSubstanceUnit. symbol: mol. It is one of the base units in SI. It is defined as follows: the *Mole* is the amount of substance of a system which *contains* as *many* elementary entities as there are atoms in 0.012 Kilograms of carbon 12. Note that, when this UnitOfMeasure is used, the elementary entities must be specified - they may be atoms, molecules, ions, electrons, etc. or groups of such particles | |
