Students will be able to explain that the density of a substance has to do with how heavy it is compared to the size of the object. Students will also be able to explain that density is a ...

Density is the mass per unit volume. Density can be found using this equation. Density is sometimes measured in g/cm 3. Make sure that you use units that are consistent with the question in an exam.

The density of an object or substance is its mass divided by its volume: Density = Mass ÷ Volume. The units of density depend on the units used for mass and volume, but are usually: g/cm³ (if mass is ...
