Sunday, April 12, 2020 Experiment 7: Apparent Molecular Weight of Air Chem100L-51 - Kimberly Tapia - Experiment 1: Study the Relationship Between Volume and Temperature for a Sample of Air 1. Took a 150 mL Erlenmeyer flask from the Containers shelf and placed it on the workbench. Double-clicked to select the option to close the flask. 2. Took air from the Materials shelf and added 1.25 atm to the flask. 3. Took a gas syringe from the Instruments shelf and attached it to the Erlenmeyer flask. Watched as air from the Erlenmeyer flask filled the gas syringe to equalize the pressure inside to the room air pressure of 1.00 atm. 4. The volume of a 150 mL Erlenmeyer flask is 182.0 mL. Note: The volume of the flask is larger than 150 mL due to the space above the top volume marking. The total gas volume is the sum of the volume of the Erlenmeyer flask plus the volume inside the gas syringe. Double-clicked on the gas syringe and read the volume. Recorded the volume of air in the syringe, the total air volume, and the temperature to reference later. - Volume of air in syringe: 45.50 mL - Total air volume: 227.5 mL - Temperature: 21.5 C 5. Took a thermometer from the Instruments shelf and attached it to the Erlenmeyer flask.
