Coal is divided into four classes anthracite bituminous subbituminous and lignite. Elemental analysis gives empirical formulas such as C 137 H 97 O 9 NS for bituminous coal and C 240 H 90 O 4 NS for highgrade anthracite. Anthracite coal is a dense hard rock with a jetblack color and a metallic luster. It contains between 86 and 98.
