Pentane (C5 H12) and hexane (C6H14) form an ideal solution. At 25°C the vapor pressures of pentane and hexane are 511 and 150 torr, respectively. A solution is prepared by mixing 25 mL pentane (density, 0.63 g/mL) with 64 mL hexane (density, 0.66 g/mL). a. What is the vapor pressure of the resulting solution? Protal = torr b. What is the composition by mole fraction of pentane in the vapor that is in equilibrium with this solution? Xpen =
