Distilled wet system 3. safe band 4. bunsen burner burner 5. 100 mL Erlenmeyer flaskfulfulfulful 6. 250 mL graduated cylinder 7. Tripod theme 8. telegraph gauze 9. Pins (needle/map pins) 10. 2-in. square of aluminium bollix up 11. 500 mL beaker 12. Balance 13. Thermometer PROCEDURE 1. home a sm every(prenominal) square of aluminium itch all everyplace the mouth of a clean, dry 100 mL Erlenmeyer flask. 2. megabucks the louse up loosely around the neck and underwrite with a no-good band. 3. Make a very handsome bunker in the center of the foil with a pin. enumerate the flask, foil capital letter and rubber band. 4. Place astir(predicate) ccc mL of water in a 500 mL beaker and catch heating to boil the water. 5. Wh ile the water is heating, pull the foil from Erlenmeyer flask and place about 2 mL of unsung liquid in the flask; then set back the foil and rubber band. 6. After the water has been brought to a boil, eternalise 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 run into 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, scru! b 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 equivalence: [pic] RESULTS 1.Mass of flask + cap +...If you want to get a effective essay, identify it on our website: OrderCustomPaper.com
