2. In a solution at 25 C, the partial molar volumes of benzene (C6H) and carbon tetrachloride (CCl4) are 0.106 L mol-' and 0.100 L mol'', respectively, at a mole fraction of 0.5. (a) What is the volume of a solution made up of one mole of each? (b) Give that the molar volumes of C6H6 and CCl4 are 0.089 L mol and 0.097 L mol", what is the change in volume on mixing 1 mole each of C6H, and CCl4? (c) What can you deduce about the nature of intermolecular forces between C6H. and CC14
