Lab # 4: Density of a Gas Safety: Goggles 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...

Density of a Gas Experiment: Materials: Test tube Stopper and delivery tube Bucket with hole and tube Analytical Balance 250mL Erlenmeyer Flask 250mL Graduated Cylinder ½ Tablet of Alka Seltzer Water

Density of a Gas Procedures: Data:

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.
