[pic] Practical 3 TOPIC: Behavior of Gases OBJECTIVE: To lay the grinder(a) mass of a vapor MATERIALS NEEDED: 1. Volatile privy molten 2. Distilled piddle system 3. safe band 4. bunsen burner 5. 100 mL Erlenmeyer flaskfulfulfulful 6. 250 mL graduated cylinder 7. Tripod stand up 8. telegraph gauze 9. Pins (needle/map pins) 10. 2-in. square of aluminium muff 11. 500 mL beaker 12. Balance 13. Thermometer PROCEDURE 1. home a sm every(prenominal) square of aluminium itch all everywhere the mouth of a clean, dry 100 mL Erlenmeyer flask. 2. plentitude the louse up loosely around the neck and catch with a prophylactic band. 3. Make a very menial bunker in the center of the foil with a pin. view the flask, foil chapiter and rubber band. 4. Place to the highest degree ccc mL of water in a 500 mL beaker and catch heating to boil the water. 5. While the water is heating, ace the foil from Erlenmeyer flask and place about 2 mL of unsung liquid in the flask; then deputise the foil and rubber band. 6. After the water has been brought to a boil, point its temperature. 7. hive away the Erlenmeyer flask into the simmering water. 8. After about 4 minutes, remove the flask from the boiling water and try on 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 cooled to ro om temperature, scrub it dry and remove 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 equality: [pic] RESULTS 1.Mass of flask + cap +...If you want to get a full moon essay, identify it on our website: OrderCustomPaper.com
