In the world of chemistry, a 'mole' is a number of a very large number of something. just as a 'dozen' is 12 of something, a 'mole' is about 6.02 * 1023 of something. in chemistry, we like to measure the number of atoms or molecules in moles. if one mole is equal to 6.02 * 1023 atoms, and you have 8.00 * 1023 atoms, then how many moles do you have? round your answer to two decimal places.
