How big is a mole in chemistry?
The mole (in chemistry) is represented by the symbol mol. It is the SI base unit which is used to measure an amount of a substance. One mole contains Avogadro’s number. Avogadro’s number is equivalent to approximately 6.022 times ten raised to the power of 23 entities. A mole is similar in concept to a dozen. In both a mole and a dozen, the units can be used to describe any set of elementary objects. However the use of a mole is usually limited to the measurement of subatomic structures, atomic structures and molecular structures. The mole represents a very large number of entities. A mole contains as many basic entities of an element as there are atoms in 0.012 kilograms of carbon-12. Avogadro’s constant is the number of atoms in twelve grams of carbon-12.
