DEFINITION:
- mole
-
1. That amount of substance (in a system) that contains as many elementary entities (e.g., atoms, ions, molecules, or radicals) as there are carbon atoms in 12 grams of carbon 12 (12C); thus one mole equals 6.023 X 1023 (Avogadro's number) elementary entities. Formerly, the connotation of mole was gram molecular weight and the two terms were sometimes used synonymously. Abbreviated mol.
2. A nevocytic nevus; the term is also used to designate a pigmented fleshy growth, and is applied loosely to any blemish of the skin.
3. A fleshy mass or tumor formed in the uterus by the degeneration or abnormal development of a fertilized ovum.
