Isopropyl Alcohol Lab Report

Satisfactory Essays
For lab twelve, the molar mass for Isopropyl alcohol is 73.121g/mol. The molar mass for unknown sample is 107.01g/mol. The molar mass for Isopropyl alcohol and unknown sample would be different from true molecular weight because the liquid of Isopropyl alcohol is not completely vaporized in boiling water. There is small amount of liquid left in the Florence flask that affect the result of molar mass for Isopropyl alcohol to be different than the true molecular weight of Isopropyl alcohol. Also, some vapors could have escaped through the pinhole. Instead of making tiny pinhole in the middle of foil, I could have accidently make a huge pinhole that causes the vapors to escape easily and change the result of molar mass. Lastly, I only did one
