Density Formula
The density (ρ) of a substance is calculated by dividing its mass (m) by its volume (V):
ρ = m / V
Where:
- ρ (rho) is the density
- m is the mass of the substance
- V is the volume it occupies
Density is typically expressed in units like g/cm³, kg/m³, or lb/ft³.
Common Material Densities
| Material | Density (g/cm³) |
|---|---|
| Gold | 19.32 |
| Lead | 11.34 |
| Iron | 7.87 |
| Aluminum | 2.70 |
| Water (4°C) | 1.00 |
| Ice (0°C) | 0.917 |
| Air (20°C) | 0.0012 |
Density determines whether a material will float or sink in water. Materials with density less than 1 g/cm³ will float.
