Disposal: Rinse and all waste in sink
Question:
What is the density of a gas (Specifically Carbon Dioxide, or CO2)?
Prediction:
The density of a gas is ______ g/mL, because it should be greater than, equal to or less than the density of a solid...

4. Density of a Gas Results/Conclusion:
Find the class average for the density of carbon dioxide and compare it to the actual density of 2.0 x 10-3 g/mL
Reach a conclusion about the relative density of a gas to a solid.
Make a particle drawing of carbon dioxide (aka dry ice) (s) and carbon dioxide (g)
List two things you could have done better (or did better the second time) in the experiment.
