Question

A piece of plastic with a mass of 15 g is

placed in a graduated cylinder. The water
level in the graduated cylinder rises from
30 mL to 55 mL when the plastic is added.
Find the density of the plastic.

Answer 1

The density of plastic is equal to 0.6 g/mL.

Step-by-step explanation:

Given that,

The mass of piece of plastic, m = 15 g

It is placed in a graduated cylinder. The water level in the graduated cylinder rises from 30 mL to 55 mL when the plastic is added.

We need to find the density of plastic.

Rise in volume = 55 mL - 30 mL

= 25 mL

The density of an object is given by :

`d=(m)/(V)\\\\d=(15\ g)/(25\ mL)\\\\d=0.6\ g/mL`

So, the density of plastic is equal to 0.6 g/mL.
