Answer:


\boxed {\boxed {\sf d= 1.3 \ g/mL}}

Step-by-step explanation:

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


d=(m)/(v)

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


m=78 \ g\\v= 60 \ mL

Substitute the values into the formula.


d=(78 \ g )/(60 \ mL)

Divide.


d= 1.3 \ g/mL

The density of the PVC pipe is 1.3 grams per milliliter
