CALCULATIONS: (NOTE: PAY ATTENTION TO UNITS!!!) + 1 Mass of Flask B + foil + air (Mass #1) 77.4564 g 2 19.7°C Temperature of air in Flask B ( Density of air at the measured temperature (read from air density table) 3 1.189 g/L 1" Mass of Flask B+ foil + CO2(Mass #2) 77.5265 g 4 5 2nd Mass of Flask B+ foil + CO2(Mass #3) 77.5270 g 6 Average of Mass of Flask B+ foil + CO2 (average of values on Row-4 and Row-5) 7 Mass of Flask B+ foil+ water (neglect air mass) 219.2123 g 8 Mass of water in Flask B (subtract Row-1 from Row-7) 9 Temperature of water in Flask B (9) 17.0°C 10 0.9989 g/ml 11 12 Density of water in Flask B (read from water density table) Volume of Flask B based on the water volume in the flask (use mass on Row-8 and density on Row-10 to calculate water volume) Mass of air at the measured temperature (use density on Row-3 and volume on Row-11 to calculate the air mass) Mass of Flask B+ foil (subtract mass of air on Row-12 from mass on Row-1) Mass of CO2 (subtract mass on Row-13 from mass on Row-6) 13 14 15 Barometric pressure (atm) 0.9883 am 16 Temperature of CO, ( 19.7 °C

17 18 Temperature of CO2 (K) (convert temperature on Row-16 from Sto K) Molar mass of CO, (use equation M-MBT/PV, mass on Row-14, temperature on Row-17, pressure on Row-15, volume on Row-11, R=0.0821LatK 'mol Molar mass of CO2 (accepted value) 19 44.0 g/mol 20 Percent error Show you calculation of the following steps. (NOTE: PAY ATTENTION TO UNITSII!) • Step 6: Average of Mass of Flask B+ foil + CO2 • Step 8: Mass of water in Flask B • Step 11: Volume of Flask B based on the water volume in the flask • Step 12: Mass of air at the measured temperature • Step 13: Mass of Flask B+ foil • Step 14: Mass of CO, • Step 17: Temperature of Co, in Kelvin • Step 18: Molar mass of CO2 accepted value-experimental value Step 20: Percent error (Note: % error *100%) accepted walue . Based on your percent error, discuss the sources of errors in your experiment
