I am trying to show that the combined weight of the reactants is equal to the combined weight of the reaction. When I placed CaCl2 into Na2 CO3 I didn't lose any weight. When I added Sulfuric Acid, I could not recork due to safety, therefore I lost Carbon Dioxide which reduced my weight. How can I safely contain the Carbon Dioxide to maintain the weight?

Why not balloon the flask instead of cork it?
Thank you!
I've never encountered this problem; however, here is a quick way although it may sound round about.
Tape to the inside of the container above the water line a small container of ascarite. That will absorb the CO2. There may be simpler ways but they don't come to mind quickly.
