Pentane (C5H12) and hexane (C6H14) form an ideal solution.
Chapter 11, Problem 57(choose chapter or problem)
Pentane (C5H12) and hexane (C6H14) form an ideal solution. At 25C 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 45 mL hexane (density, 0.66 g/mL). a. What is the vapor pressure of the resulting solution? b. What is the composition by mole fraction of pentane in the vapor that is in equilibrium with this solution?
