The density of a pure mineral is measured using various apparatus and techniques which are covered in most mineralogy textbooks.
Its specific gravity, expressed as a number representing its weight divided by the weight of an equal volume of water.
Specific Gravity is a pure number without units while density can be any number including those with decimal places with units.
Each mineral has a characteristic density (or range of densities), so if the measured density is a close match to a mineral you know, it MAY be that mineral; if it doesn't match, it is something different.
Astatine is not a mineral but a chemical element. Astatine can be obtained as a pure element but in extremely small quantities.

The density is 10.7 g/mL. The sample is not pure lead because the density of pure lead is 11.3 g/mL.
Density can tell you how "pure" a substance is. Since each substance has a specific density in its "pure" state, having no other substances in its composition, by measuring it density you can tell how pure the mineral or substance is, 99.9% pure gold.
Density is specific for each substance. Also the measurement is generally simple.
Specific Gravity is a pure number without units while density can be any number including those with decimal places with units.
Mineral density should know. Weight / density = volume
A cartridge is NOT a mineral.
Each mineral has a characteristic density (or range of densities), so if the measured density is a close match to a mineral you know, it MAY be that mineral; if it doesn't match, it is something different.
Its density is: 3.19
Theoretically a mineral is a pure substance; practically this situation is not so frequent.

Nagyagite is the only mineral with a density of 7.5
No, it doesn't.
A mineral's density increases as its mass per unit volume increases. If a mineral has a small mass and large unit volume, its density is smaller. Whereas, if a mineral has a large mass and a small unit volume, its density is greater.
