## Calculating Density of PVC Pipe

**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?**

To calculate the density of PVC, we can use the formula:

**Density (d) = Mass (m) / Volume (v)**

Given that the mass of the PVC pipe is 78 grams and it displaces 60 milliliters of water, we can substitute these values into the formula:

**d = 78 g / 60 mL**

Dividing the mass by the volume, we get:

**d = 1.3 g/mL**

Therefore, the density of the PVC pipe is 1.3 grams per milliliter.

What is the formula for calculating density?

The formula for calculating density is: Density = Mass / Volume
