A Mineralogist can learn density of the mineral from testing the mass and volume of a Mineral.
Explanation:
Earth is made up of rocks, rocks are made up of various minerals. The Mineralogist is one who studies about minerals. The minerals are classified based on their specific gravity, hardness, streak, luster and color.
The minerals are tested for density using mass and volume. It identified by Mass by Volume. All minerals are different from each other hence different density registered and difference in the specific gravity is calculated to differentiate between the minerals.
