Posted by Lindsay on Tuesday, September 8, 2009 at 8:43pm.

An unknown solute (a nonelectrolyte) was obtained and 5.37 g was weighed out. After dissolving the solute in water, the mass of the solution was 26.58 g. From the experimental results, the freezing point depression was found to be 3.6oC. If the freezing point depression constant, Kf, for water is 1.86oC.kg/mol, what is the molar mass of the unknown solute?
