Potassium fluoride is very soluble in glacial acetic acid and the solutions have a number of unusual properties. In an attempt to understand them, freezing point depression were obtained by taking a solution of known molality and then diluting it several times:

b/(mol/kg) -- delta T/K

0.015 0.115

0.037 0.295

0.077 0.470

0.295 1.381

0.602 2.67

Calculate the apparent molar mass of the solute and suggest an interpretation

Use delta H fusion = 11.4kJ/mol and T*f = 290K
