The density of a subtance is defined as its mass per unit volume.
Therefore, denisty (kg/m³) = mass (kg) / volume (m³)
Measure the density of solids:
Weigh the object using a scale. For regular objects, meeasure the dimensions to find the volume. For irregular objects, place the object in a measuring cylinder partly filled with water and work out the volume from the rise in the water level, or use a eureka can. Use the density equation to work out the density of the objects.
Measure the density of liquids:
Measure a certain volume for an amount of liquid in a measuring cylinder. Measure the mass of an empty beaker. Pour the liquid in the beaker, measure the total mass, then minus the mass of the beaker to work out the mass of the liquid. Use the density equation to work out the density of the liquid.
