Question:(adsbygoogle = window.adsbygoogle || []).push({});

For an equimolar solution of n-pentane and n-hexane, compute:

a) dew-point pressure at 120 F

b) bubble-point temperature at 1 atm

c) the vapor fraction at 120 F and 0.9 atm, and the mole fractions of the vapor and liquid phases

My attempt at a solution:

I calculated the saturation pressures of both pentane and hexane, 1.52 and 0.51, respectively. Now i don't know what to use for xi and yi. I think i need to compute the K value, but still, i am stuck. Can anyone help? thanks!
