A freezing point depression experiment was conducted using tert-butyl alcohol as the solvent instead of water The freezing point of pure tert-butyl alcohol is 27C and Kf=9.1C/mol. To 25g of tert-butyl alcohol was added 0.70 g of a non-electrolyte solute (i.e. sugar). The solution was cooled and the new freezing point was determined to be 20C. 1. What is the molar mass of the unknown non-electrolyte solute? 2. In a similar experiment, MgCl2 (MW= 95.2 g/mol) solute was added to...
