A mixture of propane and butane is fed into a furnace where it is mixed with air. The furnace exhaust leaves the furnace at 285°C, 761.0 mmHg and contains only N2, O2, CO2, and H2O. The partial pressure of O2 in the exhaust is 75.19 mmHg and the partial pressure of CO2 in the exhaust is 47.94 mmHg.
What is the mole fraction of propane in the fuel stream? (mol C3H8 / mol)
What is the mole fraction of water in the exhaust stream? (mol H2O / mol)
What is the dew point temperature of the exhaust gas? (Celsuis)
