The density of an object or substance is found by dividing its mass by its volume. The formula for density is:
Density=MassVolume\text{Density}=\frac{\text{Mass}}{\text{Volume}}Density=VolumeMass
where:
- Mass is the amount of matter in the object, measured in units such as grams (g) or kilograms (kg).
- Volume is the space that the object occupies, measured in cubic centimeters (cm³), cubic meters (m³), or other volume units.
To find density:
- Measure the mass of the object.
- Measure or calculate the volume of the object.
- Divide the mass by the volume to get the density.
For example, if an object has a mass of 200 grams and a volume of 200 cm³, the density is:
200 g200 cm3=1 g/cm3\frac{200,\text{g}}{200,\text{cm}^3}=1,\text{g/cm}^3200cm3200g=1g/cm3
Units of density depend on the units used for mass and volume but common ones include g/cm³ for smaller objects or kg/m³ for larger objects.
