A solution is prepared by mixing 50.0 mL toluene (C6H5CH3, density = 0.867 g/mL, 92.13 g/mol) with 125 mL benzene (C6H6, density = 0.874 g/mL, 78.11 g/mol). Assume that the volumes are additive upon mixing (meaning that the total volume equals the sum of the volume of toluene plus the volume of benzene). Please calculate the mass percent (weight % by mass), mole fraction, molality, and molarity of toluene.
