mole-in-term-of-mass-volume Thus a mole represents the quantity of material, which contains one Avogadro's number of chemical units of any substance. The unit of mole is denoted as 'mol'. One mole of atoms = 6.023 x 1023 atoms = Gram atomic mass of the element. One mole of
AQA chemistry specification, Amount of substance - The mole and the Avogadro constant (L)
A BBC Bitesize secondary school revision resource for Higher Chemistry on calculations: moles, Avogadro constant, calculating molar volume, reactant gas.
Mole is defined as the amount of a substance, which contains the same number of chemical units (atoms, molecules, ions or electrons) as there are atoms in exactly 12 grams of pure carbon-12. A mole represents a collection of 6.023 x 1023 ( Avogadro's number) chemical units. Thus a mole represents the quantity of

The IUPAC traditionally defines mole as “SI base unit for the amount of substance (symbol: mol). The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon-12. When the mole is used, the elementary entities must be specified and may be
Chemguide: Support for CIE A level Chemistry. Learning outcome 1(b). This statement deals with the mole concept and the Avogadro Constant. Before you go on, you should find and read the statement in your copy of the syllabus. For the examples which follow on this page, you will also need to refer to the Periodic Table
The charge that each electron carries is 1.60 x 10-19 coulombs. You can find that figure in the Data Booklet which you will have in an exam. You will find a copy towards the end of the syllabus. 1 mole of electrons contains the Avogadro constant, L, electrons - that is 6.02 x 1023 electrons. That is also in the Data Booklet.
Chemguide: Support for CIE A level Chemistry. Learning outcome 6.2(d). This statement is about finding a value for the Avogadro constant by doing simple electrolysis reactions. Before you go on, you should find and read the statement in your copy of the syllabus. What follows assumes that you have read and understood
