Understanding Density: The Core Concept
What Is Density?
Density is a measure of how much mass is contained within a specific volume of a substance. It is expressed mathematically as:
- Density (ρ) = Mass (m) / Volume (V)
where:
- ρ (rho): Density
- m: Mass of the object or substance
- V: Volume of the object or substance
Units of Density
Density can be expressed in various units depending on the context and the substance involved, including:
- grams per cubic centimeter (g/cm³)
- kilograms per cubic meter (kg/m³)
- grams per milliliter (g/mL)
