A coal sample has a mass analysis of 80.4% carbon, 3.9% hydrogen (H2), 5.0% oxygen (O2), 1.1% nitrogen (N2), 1.1% sulfur, and the rest is noncombustible ash. For complete combustion with 120% of the theoretical amount of air, determine (a) the airfuel ratio on a mass basis, (b) the amount of SO2 produced, in kg per kg of coal.
