A piece of PVC plumbing pipe displaces 60 mL when placed into a container of water. If the pipe has a mass of 78 g, what is the density of PVC?

Explanation:

Density can be found by dividing the mass by the volume.

The mass of the pipe is 78 grams. It displaced 60 milliliters of water, therefore that is the volume.

Substitute the values into the formula.

Divide.

The density of the PVC pipe is 1.3 grams per milliliter
