There are 5.418 * 10^24 atoms in 3 moles of Carbon Dioxide

Explanation:

1 Mole is 6.02*10^23 molecules

Therefore 3 Moles of Carbon Dioxide CO_2 = 3(6.02*10^23) or 18.06*10^23 molecules of CO_2

There is one atom of Carbon and two atoms of Oxygen in each molecule of Carbon Dioxide CO_2

Therefore there are three atoms in each molecule.

(3 atoms)18.06*10^23 molecules = 54.18 * 10^23 atoms

or

5.418 * 10^24 atoms
