Example: Convert 1.50 moles of CO_{2} gas to molecules. 
We know that there are 6.022 x 10^{23} (Avagadro's number) atoms in one mole. In order to find out how many molecules are in the amount of moles we were given, you can multiply. It will look like this: 
1.50 mol CO_{2} x 6.022 x 10^{23 }molecules CO_{2}/1 mol CO_{2}= 9.03 x 1023 molecules CO_{2} 
This is what it looks like on paper.
