#### The Density of Common Rocks and Minerals

The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

#### Difference Between Density and Specific Gravity

However, because the density of pure water is so close to 1 (0.9976 grams per cubic centimeter), specific gravity and density are nearly the same value so long as the density is given in g/cc. Density is very slightly less than specific gravity.

#### Solved: For Identifying Minerals, Specific ... - Chegg.com

For identifying minerals, specific gravity is one of the more diagnostic features. Specific gravity is a measure of the density (r) of a mineral since it is defined as the ratio between the weight of a volume of the mineral and the weight of an equal volume of water. However, it is easy to confuse density with mass (m) or weight.

#### MINERAL GALLERY - SPECIFIC GRAVITY

Specific gravity is a unitless measure, because it is derived from the density of the mineral divided by the density of water and thus all units cancel.
