A medium-grade bituminous analyzes as follows: Component S = 2 percent(wt) Component N = 1 percent (wt) Component O = 6 percent (wt) Component Ash = 11 percent (wt) Component water = 3 percent (wt) Component Residuum = 77 percent (wt) The residuum is C and H and the mole ratio in the residuum is H/C = 12 Calculate the mass fraction and mole fraction of the coal excluding ash and water
