Just as a 'dozen' 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 7.00 * 10^23 atoms, then how many moles do you have?

6.02*10^23  to 7.00*10^23

You can just cancel out the 10^23 on both sides to make it easier.

6.02 to 7.00

in this case you will divide what you have (7) by what one is equal to (6.02)

7 / 6.02 = 1.16279069767 or approximately 1.163 or 1 and 49/301 or, for the most simplified fraction, 1 and 7/43
