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.

A planet’s mass and volume are easy to determine. Because planets are nearly spheres, we can calculate volume from our knowledge of a planet’s radius, which we determine by measuring both the planet’s ...
