2020-4-20 · The mole, symbol mol, is the SI unit of amount of substance. One mole contains exactly 6.022 140 76 x 10 23 elementary entities. This number is the fixed numerical value of the Avogadro constant, N A, when expressed in the unit mol –1 and is called the Avogadro number. The amount of substance, symbol n, of a system is a measure of the number of specified elementary entities.

The SI unit of volume is the cubic meter (m 3), which is a derived unit. Liter (L) is a special name for the cubic decimeter (dm 3). The symbol for the liter is uppercase letter “ell” (L) is preferred to avoid the risk of confusion between the lowercase letter “ell” (l) and the number one (1).
