Kindly give the correct answer I will upvote.

A mixture of propane and butane is fed into a furnace where it is mixed with air. The furnace exhaust leaves the furnace at T3 = 287 C, Pz = 787.0 mmHg and contains only N,, 02, CO2, and H, 0. The partial pressure of O, in the exhaust is Po, = 10.39 mmHg, and the partial pressure of Co, in the exhaust is pco, = 85.78 mmHg. = n CH CH 10 Furnace T, P, ng CO ,0 0, N, n N 0, What is the mole fraction of propane in the fuel stream? 0.3268 mole fraction: mol CH /mol Incorrect What is the mole fraction of water in the exhaust stream? mole fraction: 0.13854 mol H2O/mol What is the dew point temperature of the exhaust gas? 46.25 dew point temperature: C Incorrect
