Jan 31, 2014 · Calculate the molarity, molality, and moles fraction of each of the preceding reagents. A solution is prepared by mixing 25mL pentane (C5H12, d = 0.63g/cm3) with 45mL hexane (C6H14, d = 0.66g/cm3). Assuming that the volumes add on mixing, calculate the mass percent, mole fraction, molality, and molarity of the pentane. ................
