The purpose for executing such an experiment is to find out the molecular mass of a volatile liquid. I would hypothesize that if the experiment is completed with out a hitch, the results will be indicative of its relation to temperature of boiling, pressure, volume, weight, and the correct constant. The main special technique or skills demonstrated in this experiment are; the usage of the ideal gas law, and the lab skills of evaporation and compensating.

Procedure

Fit a piece of aluminum foil around a small test tube and poke a small hole in the top

After finding the tube's mass put 0.5 mL of the unknown in the test tube.

Put the test tube in a bath of heating water until the water boils

Record the boiling temperature and continue until three minutes after the unknown is evaporated.

Immediately cool the test tube in cool water and...
