Nick Rotruck 2/11/08 QUESTION: How do you find the molecular formula of an unknown alcohol? HYPOTHESIS: I believe that by turning the alcohol into a gas and finding the mass of the vapor, you can find the molar mass that us very close to the actual molar mass. Also, I think that after finding the molar mass of the alcohol C 2 H 6 O, I can also find the molecular formula. PROCEDURE: 1. Brought a 1000-mL beaker that was 2/3 full of water to a boil. Lowered an Erlenmeyer flask with 3 mL of an unknown alcohol into the boiling water. 2. After all the liquid alcohol had turned into vapor, removed the flask found the mass of the vapor. Then, used the ideal gas law to find the molar mass of the alcohol. 3. Repeated steps 1 and 2 for a second trial. Then, took the average of the two molar masses. 4. After being told the empirical formula of the alcohol was C 2 H 6 O, found the molecular formula from the molar mass. 4
