Although coal is a complex mixture of substances, its elemental composition can be approximated by the formula ??. Using this chemical formula, how would you calculate the percent by mass of oxygen in coal?
A) [(9 g) / (135 (12 g) + 96 (1g) + 9(16 g) + 14g + 32g)] x 100
B) [(9 x 16 g) / (135 (12 g) + 96 (1g) + 9(16 g) + 14g + 32g)] x 100
C) [(135 x 12 g) / (135 (12 g) + 96 (1g) + 9(16 g) + 14g + 32g)] x 100
D) [(96x 1 g) / (135 (12 g) + 96 (1g) + 9(16 g) + 14g + 32g)] x 100
