Question

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

Answer 1

Use the equation d=m/v

your mass or "m" is 78 g

your volume or "v" is 60mL

if you plug those values into the equation it will look like this:

d=78/60

d=1.3g/mL should be what you come up with
