A solution is prepared by dissolving 0.5150 g of a solute (MW = 110.1) in 100.0 g
Question:
A solution is prepared by dissolving 0.5150 g of a solute (MW = 110.1) in 100.0 g of an organic solvent (MW = 94.10). The solution is observed to have a freezing point 0.41°C below that of the pure solvent. A second solution is prepared by dissolving 0.4460 g of a solute having an unknown molecular weight in 95.60 g of the original solvent. A freezing point depression of 0.49°C is observed. Compute the molecular weight of the second solute and the heat of fusion (kJ/mol) of the solvent.
