Conversions: Moles to Molecules
Example: Convert 1.50 moles of CO2 gas to molecules.
We know that there are 6.022 x 1023 (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 CO2 x 6.022 x 1023 molecules CO2/1 mol CO2= 9.03 x 1023 molecules CO2
This is what it looks like on paper.
