Question
During a freezing point depression experiment to determine the molar mass of an unknown solute (assume the van 't Hoff factor = 1.0000), the measurements in the below table are made.

Complete the table
   
mass of test tube + beaker + stir bar + solvent (g) 30.48
mass of test tube + beaker + stir bar + solvent + solute (g) 38.25
mass of test tube + beaker + stir bar (g) 10.06
mass of solvent (g) (A) 
mass of solute (g) (B) 
   
freezing point pure solvent (ºC) 45.31
freezing point solution (ºC) 41.51
 


If the freezing point depression constant of the pure solvent is 8.68 ºC·kg solvent/mol solute, calculate the molar mass of the solute
 g/mol
