| Micromole | A mole is a measure of units, not weight. One mole = 6.023 x 10^23 (10 to the 23rd power) units - also known as Avogadro's number. It is used in chemistry to establish atomic or molecular weight. For example, 1 mole of carbon = 12 grams. If you look at a periodic table, you'll see carbon has an atomic weight of 12. A mole of water would be 18 grams (2 grams hydrogen + 16 grams oxygen). A micromole is one millionth of a mole. |
