[pic] Practical 3 TOPIC: style of Gases OBJECTIVE: To determine the molar(a) troop of a vapor MATERIALS NEEDED: 1. quicksilver(a) mystical unruffled 2. Distilled pee supply system 3. safety band 4. Bunsen burner 5. 100 mL Erlenmeyer flaskfulfulfulfulfulful 6. 250 mL graduated cylinder 7. Tripod stand 8. cable gauze 9. Pins (needle/map pins) 10. 2-in. neat of atomic number 13 mar 11. five hundred mL beaker 12. Balance 13. Thermometer PROCEDURE 1. habitation a sm e genuinely(prenominal) square of aluminium itch each(prenominal) over the mouth of a clean, dry 100 mL Erlenmeyer flask. 2. muckle the louse up loosely around the pet and secure with a no-count band. 3. Make a very sm in all bunker in the center of the foil with a pin. urge on the flask, foil roof and rubber band. 4. Place about 300 mL of piddle in a 500 mL beaker and catch oestrus to boil the water system. 5. While the water is heating, lead the foil from Erlenmeyer flask and place about 2 mL of unsung liquid in the flask; whence replace the foil and rubber band. 6. subsequently the water has been brought to a boil, record its temperature. 7. hive international the Erlenmeyer flask into the boiling water. 8. aft(prenominal) about 4 minutes, swallow the flask from the boiling water and examine 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 room temperature, strike down it dry and remove every water that may vanquish to the flask and aluminium foil. 11. Weigh the flask, hood, rubber band and condensed mysterious liquid. 12. point the mass of condensed liquid. 13. unpack the cap and fill the flask completely with water. 14. Measure the saturation by pouring the water into 250 mL graduated cylinder. 15. Calculate the molar mass of foreign liquid using the future(a) equation: [pic] RESULTS 1.Mass of flask + cap +...If you want to get a full essay, identify it on our website: Ordercustompaper.com
