Avogadro's number, or constant, is the number to which the mass of an atom must be multiplied to give a mass in grams numerically equal to its relative atomic mass that sounds like a mouthful, but it just means that an avogadro number of carbon atoms has a mass of 12g, because the relative mass of carbon = 12. Mr carson's science page avogadro's constant & the mole the mole concept will even allow us to compare the number of atoms in various substances.

It is the number of particles present in exactly 12 grams of the isotope carbon-12 called the avogadro constant the mole the mole concept and avogadro's constant.
Avogadro’s number is defined as the number of elementary particles (molecules, atoms, compounds, etc) per mole of a substance it is equal to 6022×10 23 mol-1 and is expressed as the symbol n a avogadro’s number is a similar concept to that of a dozen or a gross a dozen molecules is 12 molecules a gross of molecules is 144 molecules. Avogadro’s constant is the number of particles (atoms or molecules) in one mole of any substance for example, 12 grams of carbon contains 602214129 x 10 23 carbon atoms avogadro’s constant is an enormous number. The avogadro constant is a huge number (approximately 602 x 10 23) it has units of mol-1, which you would read as per mole in other words, there are 602 x 10 23 of whatever formula units you are talking about per mole of that formula.
