A gas mixture containing 25.3%CH4,25.6%CO,10.7%CO2,14.8%H2, and the balance being argon is burned with 16.5% excess dry air. If complete combustion is achieved, what is the dew point of the flue gas if it exits at 1.80atm ? Type your answer in C,2 decimal places. logP(mmHg)=AC+T(C)BA=8.07131B=1730.63C=233.426
