WebA mole (symbol mol) is defined as the amount of substance that contains as many atoms, molecules, ions electrons or any other elementary entities as there are carbon atoms in exactly 12 gm of 12 C . The number of atoms in 12 gm of 12 C is called Avogadro’s number (N A ). N A = 6.023 x 10 23 WebMole Concept Summary Mole: Mole is the measurement in chemistry. It is used to express the amount of a chemical substance. One mole is defined as the amount of substance of a system which contains as many entities like, atoms, molecules and ions as there are atoms in 12 grams of carbon - 12". Web• The Mass of 1 mole (in grams) Atoms • Equal to the numerical value of the average atomic mass (get from periodic table) 1 mole of C atoms = 12.0 g Molecules • Mass in grams of 1 mole equal numerically to the sum of the atomic masses. 1 mole of H 2 O = ? g 2 moles H x 1 g + 1 mole O x 16 g = 18 g H 2 O Molar Mass browne mixing bowls
