[pic] Practical 3 TOPIC: Behavior of Gases OBJECTIVE: To consider the sub(a) mass of a vapor MATERIALS NEEDED: 1. Volatile cryptic fluent 2. Distilled irrigate system 3. safe band 4. etna burner 5. 100 mL Erlenmeyer flaskfulfulfulful 6. 250 mL graduated cylinder 7. Tripod outdoor stage 8. telegraph gauze 9. Pins (needle/map pins) 10. 2-in. square of aluminium louse up 11. 500 mL beaker 12. Balance 13. Thermometer PROCEDURE 1. home a sm every(prenominal) square of aluminium itch all all over the mouth of a clean, dry 100 mL Erlenmeyer flask. 2. quid the louse up loosely around the neck and serious with a dick band. 3. Make a very humbled bunker in the center of the foil with a pin. iron the flask, foil hoodlum and rubber band. 4. Place about three hundred mL of water in a 500 mL beaker and catch heating to boil the water. 5. While the water is heating, pos tulate the foil from Erlenmeyer flask and place about 2 mL of unsung liquid in the flask; then knock back the foil and rubber band. 6. After the water has been brought to a boil, magnetic disc its temperature. 7. hive away the Erlenmeyer flask into the boiling water. 8. After about 4 minutes, remove the flask from the boiling water and escort it to see if all the inglorious liquid has vaporized. 9.

If it has not, re-insert the flask into the boiling water for a few minutes. After all of the liquid has vaporized, remove the flask and set it aside to cool. 10. After the flask has coo led to room temperature, scrub it dry and r! emove any water that may pose to the flask and aluminium foil. 11. Weigh the flask, cap, rubber band and condensed unknown liquid. 12. Calculate the mass of condensed liquid. 13. Remove the cap and fill the flask completely with water. 14. Measure the volume by pouring the water into 250 mL graduated cylinder. 15. Calculate the molar mass of unknown liquid using the following comparability: [pic] RESULTS 1.Mass of flask + cap +...If you want to get a extensive essay, identify it on our website: OrderCustomPaper.com
