A 0.2 molar solution of a solute X, in benzene, displays an osmotic pressure given by the formula Π = (0.1)RT. Which of the following is most likely to be the case? A) X exists in benzene as X₂. B) X exists in benzene as X. C) X exists in benzene dissociated into two particles. D) This solution strongly deviates from ideal behavior. E) None of these explanations is plausible.
