Alka Seltzer and the Ideal Gas Law

    The purpose of this lab was to determine the mass of the CO2 produced. Using a balloon and 3 Alka Seltzer tablets, we were able to measure the amount of CO2 by measuring the circumference of the balloon and filling it with water till it matched the circumference of the Alka Sletzer tablet sized balloon. 

Analysis Questions

1. We spilled some powder and spilled water on the first attempt.

2. Spilling powder would make "n" a smaller quantity.

3. The volume was 896 cm3/mL.

4. It was mucho close. I believe the actual one is accurate because the balloon is not a perfect sphere.

5. A real gas interacts with others while an ideal is independent of others. In an ideal gas actual volume taken up by the molecules of gas is not taken into account. 

6. No, the ideal gas would not interact with others.

Advanced Questions

1. 2.06 grams is the mass of CO2 that should be collected.

2. 76.7% is the percent yield for the for the CO2. 

3. Our calculations would mean it was less than the actual value since the CO2 dissolved.
