Pentane (C5H12) and hexane (C6H14) form an ideal solution. At 25ºC 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?
