In Chemistry the quantities of a dozen, a century, a gross, ream and millennium are far too small. Even a million is too small. One million atoms of iron weighs 0.0000000000000000928 grams! Chemistâs measure atomic particles using a large QUANTITY called the mole. One mole is equal to 602214179000000000000000 or 6.022 x 1023 particles.
Etymology: L, molecula, small mass. the standard unit used to measure the amount of a substance. A mole of a substance is the amount containing the same number of elementary particles as there are atoms in 12 g of carbon 12, typically 6.02 Ã 1023 particles. This number is called Avogadro's number. Also spelled mol.
