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.

But what does that mean? The simple answer is how heavy something is for its size. If something seems very heavy for its size (like a heavy metal object), we say it is more dense. If something seems ...

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 ...
