What is Molar Mass Determination via Freezing Point about?

The purpose of the experiment was to determine the molar mass of an unknown alcohol. The procedure was modified from the lab manual and involved measuring the freezing point depression of the unknown alcohol in tert-butyl alcohol (TBA). Data tables showed the temperature over time for TBA and the alcohol. Calculations using the freezing point depression equation yielded a molar mass of 145 g/mol for the unknown alcohol, identified as ethyl benzene. Sources of error in the experiment included measurements of
