On this page you will find information on how to convert the number of atoms in a sample by mass, and describe Avogadro's number in terms of the mole.
How big is a mole? (Not the animal, the other one.)
Just How Small is an Atom?
The Number of Particles
The amount of atoms that are contained in tip of a needle are greater than the number of stars in the night sky...
think about that for a moment...
The way that chemists count atoms is similar to the way chicken farmers count eggs.
one dozen
=12
one mole
=602,200,000,000,000,000,000,000 (602 sextillion)
