Chapter 13, Problem 14P(choose chapter or problem)
A coal sample has a mass analysis of 80.4% carbon, 3.9% hydrogen (H), 5.0% oxygen (O), 1.1% nitrogen (N), 1.1% sulfur, and the rest is noncombustible ash. For complete combustion with 120% of the theoretical amount of air, determine the air–fuel ratio on a mass basis.
