The mole is the SI unit for amount of substance. It is defined as a number - that number of atoms which exists in exactly twelve grams of the isotope of carbon of isotopic mass twelve. For historical reasons this number is known as the Avogadro number; its symbol is NA. Although the Avogadro number is very large, it can be measured with high precision; the currently accepted value is 6.0221367(36) x 10+23 entities/mole.
