Question

DATA & CALCULATIONS: Measured quantities that were the same for all three runs: 138.5 mL Volume of flask Laboratory temperature Atmospheric pressure Density of air 29.82 inches Hg 1.189 g/L Run 1 Run 2 Run 3 Step 1 Mass of stoppered flask plus air,g 110.9888 107.7244 100.000 Step 4 Mass of stoppered flask plus CO2.9 111.0708 107.8038 100.0810 Step 8 Volume of air or CO2 in flask, L Step 7 Laboratory temperature, K Step 7 Atmospheric pressure, atm Step 8 Density of air, g/L Step 9 Mass of air. 9 (step 8 x step 6) Step 10l Mass of stoppered flask (step 1 - step 9) Step 11 Mass of CO2 g (Step 4 - Step 10) Step 12 Corrected volume of C, At STP.L 44.01 44.01 44.01 mass of CO2 g/mole Step 14 Moles of CO2 (Step 11 / Step 13) Experimental Molar volume. L Step 15 (Step 12 / Step 14) Step 10 Theoretical molar volume. L 2241 2241 2 2.41 Step 17 Percent error

The steps just refer to the lab procedure and the ones present are where data is actually recorded. The rest, like step 5, are things like fill the flask with water and wipe away any excess. All needed info for the calculations is there. I'm trying to double-check my work.
