: Density and its Applications Chemistry LibreTexts

The general meaning of density is the amount of anything per unit volume. What we conventionally call the "density" is more precisely known as the "mass density". Density can be expressed in any combination of mass and volume units; the most commonly seen units are grams per mL (g mL –1, g cm –3), or kilograms per liter.

rock | Definition, Characteristics, Types |

Rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is comprised and typically form recognizable and mappable volumes. Rocks are commonly divided into three major classes according to the processes that resulted in their formation.

Understanding porosity and density

Density is defined as the mass per volume. In rocks, it is a function of the densities of the individual grains, the porosity, and the fluid filling the pores. There are three types of density in rocks: dry density, wet density, and grain density. The data table lists the dry, wet, and grain densities of the samples.

Density Specific Gravity

Specific gravity is the ratio of the mass (weight) of a rock to the mass of the same volume of water. Water has a density of g/cm 3, so the numeric value of specific gravity for a rock is the same as that for density. Because specific gravity is a ratio, it has no unit. Specific gravity is easier to measure than density.
