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

Nov 12, 2016

There are $5.418 \cdot {10}^{24}$ atoms in 3 moles of Carbon Dioxide

#### Explanation:

1 Mole is $6.02 \cdot {10}^{23}$ molecules

Therefore 3 Moles of Carbon Dioxide $C {O}_{2}$ $= 3 \left(6.02 \cdot {10}^{23}\right)$ or $18.06 \cdot {10}^{23}$ molecules of $C {O}_{2}$

There is one atom of Carbon and two atoms of Oxygen in each molecule of Carbon Dioxide $C {O}_{2}$

Therefore there are three atoms in each molecule.

(3 atoms)$18.06 \cdot {10}^{23}$ molecules $= 54.18 \cdot {10}^{23}$ atoms

or

$5.418 \cdot {10}^{24}$ atoms
