WebObserved molar mass is greater than the predicted value: The observed value of molar mass is lesser than the normal value. The value of the Van’t Hoff factor is less than one. The value of i is greater than one. The values of the colligative properties are lower than expected. Example: reduced boiling point and freezing point. WebMay 12, 2016 · So nonane, and 2,3,4-trifluoropentane have almost identical molar masses, so 128 versus 126 grams per mole, but nonane has a significantly higher boiling point. So we can see that nonane has a boiling point of 151, versus 89 Celsius for our TFP.
