In the world of chemistry, a 'mole' is a number of something... a very 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? Round your answer to two decimal places.

Given:

No of atoms present= 8.022 x 10^23 atoms

Now we know that 1 mole= 6.022 x 10^23 atoms


Hence number of moles present in 8.022 x 10^23 atoms is calculated as below.

Number of moles

= 8.022 x 10^23/6.022x 10^23

=1.3 moles.

Hence we have 1.3 moles present.
