A solution which is composed of heptane (C-H16, 100.198 g mol") and octane (CH13, 114.224 g mol-) has vapor pressure of 78 torr at 40 °C. The saturated vapor at equilibrium with the solution contains 16.55 g heptane and 22.15 g octane. The vapor pressures of pure heptane and pure octane at 40 °C were 92.0 Torr and 31.2 Torr, respectively. What is the mole percent of C3H;3 in the initial solution? Do not write units, only enter numerical values. Use two digits at most for decimal numbers, use dot (.) as decimal separator (i.e. two-point-fifty-one should be entered as 2.51).
