What would the number for mole (mol) be compared to?

Question

For chemistry Mole is the number of atoms in one gram of a substance what would that number be compared to?

Answer 1

The mole is 6.022 X 10^22 it is a huge number the only thing that it can be compared to would be other atoms per gram, and possibly a fraction of the stars in the universe, it is a huge number! its hard to contemplate it!  

Answer 2

No, the mole is the amount of substance that contains the same number of elementary particles contained in 12 g of 12C (isotope 6 protons and 6 neutrons). That number of particles is 6,022 x 10^23 (Avogadro's number)

1 mole of H2O contains 6,022 x 10^23 molecules of H2O

3 moles of Cl2 contain 3 x 6,022 x 10^23 molecules of Cl2

that means 2 x 3 x 6,022 x 10^23 atoms of Chlorine
