Answer:

Debbie can take the following step

1. Find the mass of the substance in kilograms by measuring on a chemical balance and record

2. Fine the volume of the plastic(m^3). if it is a cylindrical plastic, volume will be area multiplied by height( $\pi r^{2} h$ )

3. Density of a substance is the ratio of the mass of a substance to its volume.Find its density and record

4. Compare the density of the substance to that of water which is 1000kg/m^3.
