Question

Lab 5 Post-Lab - Properties of CO2 and the Determination of NaHCO3 (2pts) Determination of Carbon Dioxide How will you collect data for this experiment? virtually Mass of system before reaction (g) Mass of system after reaction (g) Temperature CO2(g) in °C Atmospheric pressure in lab (mmHg) Volume (mL) CO₂(g) Data 95-740 95.500 25.0 756 124.7 (7pts) Calculations Calculations Mass of CO2 gas (g) Volume of CO₂ (L) Density CO2 (g/L) Calculations (0/1pts) 1.State the theoretical density of CO2 (g/L) and then state the temperature and pressure of this value in the essay field below. Also, include the source of your value. 2.State the temperature and pressure of your theoretical density value, includind the source of your value 3.Calculate the percent error of your density. (8pts) Molar mass carbon dioxide Calculate the molar mass of CO2 using the ideal gas law and mass of CO2. Use the true gas constant, o.08206 L-atm/mol·K. To determine the vapor pressure of water, use this table. Molar mass of CO2 Calculations Vapor pressure of water in (mmHg) Partial pressure of CO2 (torr) Partial pressure of CO2 (atm) Temperature of CO2 (K) Moles of CO2 Experimental Molar mass CO2 (g/mol) Theoretical Molar mass CO2 (g/mol) Percent Error (6pts) Post-lab Questions (pending/2pts) 1. Describe how close your experimental values were to the actual values for density and molar mass. Saved (pending/2pts) 2. Explain two possible reasons for the differences between your values and the actual values. (pending/2pts) 3. If the percent errors were different for density and molar mass, give one possible reason for why one was closer than the other. Saved (10pts) Part 2 - Determination of the Purity of a Sodium Bicarbonate Sample Report (pending/10pts) Upload the group report here. It should include the following: Header information 1. 2. Problem being solved 3. Summary of the procedure 4. Detailed procedure 5. Data table for Part 2 (including units) 6. 7. 8. Statement of % Purity of the sample Discussion of your answer with evidence Answer to the neutralization reaction
