Pentane (C5H12) and Hexane (C6H12) form an ideal solution. At 25 degrees C the vapor pressures of pentane and hexane are 511 and 150.0 torr. A solution prepared by adding 44.4 mL of pentane to an unknown volume of hexane results in a vapor pressure of 470.6 torr. Determine the volume of hexane in mL. Density of pentane is 0.63 g/cm3. Density of hexane is 0.66 g/cm3
