3.3.1 Moist Specific Gravity, Raw Coal Density. Moist specific gravity refers to the specific gravity of raw coal and is determined on a block of bed-moist coal (300-500 g) by weighing the block in air and then in water, i.e. it equals Wa/(Wa-Ww) where Wa and Ww are the weights in air and water respectively.

"Specific gravity" is the density of a material relative to water. Since rocks are comprised of several distinct mineral phases, they do not have a fixed specific gravity. Instead, a rock's "bulk density" arises as a result of the percentage of all minerals in a sample multiplied by the specific gravity of each.
