Question

3.00 mol of carbon dioxide is equal to how many atoms?

Answer 1

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
