Density of Galena: Specific Gravity and Mohs Hardness
The density of galena is about 7.5 g/cm3, equal to a specific gravity of 7.5, with a Mohs hardness near 2.6. One cubic meter of solid galena weighs roughly 7.50 tonnes.
| Property | Value |
|---|---|
| Density | 7.5 g/cm3 |
| Specific gravity | 7.5 |
| Mohs hardness | 2.6 |
| Mass of 1 m3 | about 7.50 tonnes |
Why it matters
Lead sulfide, and the densest common mineral most people ever hold; a density log spike in miniature. Mineral densities are the building blocks of rock density: weight them by volume fraction and the bulk rock number follows, which is exactly what the calculator below does.
