Materials:
500 ml Erlenmeyer flask 1000 ml beaker Hot plate Aluminum foil
Needle
Unknown liquid sample (CH3OH)
Ring stand and beaker clamp
Procedure:
1) Prepare 1000 ml beaker by filling with water and heat to boiling on the hot plate …show more content…
11) Add more unknown and repeat experiment (if time permits)
12) Rinse flask and fill with water completely
13) Take the temperature to find density
14) Mass flask and water to find mass of water
15) Find volume of Flask
