Answer:

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
