In this reaction, baking soda acts as a base, and takes a proton from vinegar, which is an acid. The reaction releases gas because when the baking soda receives the proton, it transforms into water and carbon dioxide.
In order to react vinegar and baking soda to yield 200 Liters of gas, you would need to completely react 8.9 moles of vinegar, approximately 530 mL, or 2.24 cups. Remember in order to get this much gas you will need to react the vinegar completely, thus you will need an excess of baking soda.
