Here’s a good hint for you.
One mole of a gas (the molecular wieght in grams) is 22.4 liters at STP (Standard temperature and pressure).
For example H2 (Hydrogen) is 2 so 2 grams of hyrogen is 22.4 liters @STP

What about CO2? 12 + 16 +16 = 44 so 44 grams of CO2 is 22.4 liters @STP.

This should get you going.
