Explain giving examples the term \'colligative molality\'. Why do we sometimes get abnormal molecular masses of the substances using colligative properties of the solution? The freezing point depression of `0.1` molal solution of benzoic acid in benzene is `0.526K`. For benzene `K_(f)` is `5.12K kg \"mol\"^(-1)`. Calculate the value of van\'t Hoff factor for benzoic acid in benzene. What conclusion can you draw about the molecular state of benzoic acid in benzene?
