a level chemistry avogadro's constant
12 Jun 2017 Avogadro's number is used in chemistry calculations. Here is a definition of Avogadro's number and its value.
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

That is also in the Data Booklet. This value is known as the Faraday constant. You will see that the syllabus statement quotes the formula F = Le, where F is the Faraday constant, L is the Avogadro constant and e is the charge on an electron (in terms of the number of coulombs it carries).
The value I will use for Avogadro's Number is 6.022 x 1023 mol?1. Types of problems you might be asked look something like these: 0.450 mole (or gram) of Fe contains how many atoms? 0.200 mole (or gram) of H2O contains how many molecules? When the word gram replaces mole, you have a related set of problems

1 mole of any of these contains exactly the same number of the formula units you have written - the same as the number of atoms in 12 g of the carbon-12 isotope. That number is called the Avogadro Constant, and is given the symbol L. The Avogadro Constant is a huge number (approximately 6.02 x 1023).
