Solution: A solution is prepared by mixing 50.0 mL toluene (C6H5CH3, d = 0.867 g/cm3) with 125 mL benzene (C6H6, d = 0.874 g/cm3). Assuming that the volumes add on mixing, calculate the mass percent, mole fract

A solution is prepared by mixing 50.0 mL toluene (C₆H₅CH₃, d = 0.867 g/cm³) with 125 mL benzene (C₆H₆, d = 0.874 g/cm³). Assuming that the volumes add on mixing, calculate the mass percent, mole fraction, molality, and molarity of the toluene.
