in the world of chemisty, a 'mole is a number of something ... a very lary large number of something.

just as a dozen is 12 of something, a mole is about 6.02 * 10^23 of something .

in chemistry, we like to measure the number of atoms or molecules in moles.

if one mole is equal to 6.02 * 10^23 atoms, and you have 8.00 * 10 ^23 atoms, then how many moles do you have ?
