Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL.

What do you use to measure density?

A hydrometer is a special device used to determine the density of liquids.

How do you find the density?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

Density is calculated as the mass of an object divided by its volume (d = m/V). Density is an important concept because it allows us to determine what substances will float and what substances will sink when placed in a liquid.
