I would appreciate help with this thermodynamics problem, since I have seen several answers right here on chegg and I can't get to the correct result, please take your time to answer the question correctly.

A mixture of 40 mol% isobutane and 60 mol% pentane flows into a chamber, is ignited at 49C and 3.2 bar, and exits as two streams, one as a gas, the other as a liquid. Find how much liquid leaves per mole of incoming feed and the composition of the outgoing streams. USE K VALUE. K1= ? K2=? L=? X1=? Y1=?

I saw these results from some other question, I hope I can help you answer, L=0.8 x1 = 0.33 x2 = 0.67, V = 0.2 y1 = 0.67 y2 = 0.33
