Help with Carbon Dioxide Lab

Research:Search, " What role does carbon dioxide play in forming limestone as a chemical precipitate?"



Hypothesis: This is based on 44% of the shell mass.


The conclusion should reflect the hypothesis and explain how the density formula was used to check the accuracy of the calculated mass of the CO2 .

The predicted mass of the CO2 was based on the calculation that 44% of ___ g of CaCO3 (shell) should produce ___ g of CO2. Lab results showed that each gram of shell produced _____ mL of CO2. Using the density formula and the known density of CO2 as a gas 0.001977 g/mL the predicted mass was off by ____ %.
