- A penny

- A graduated cylinder

- Water

- A scale

Procedure:

1. Fill the graduated cylinder with water to the 10 mL mark.

2. Drop the penny into the graduated cylinder.

3. Note the new water level.

4. Subtract the initial water level from the final water level to determine the volume of the penny in milliliters.

5. Weigh the penny using the scale.

6. Divide the mass of the penny by its volume to determine its density.

Density is mass/ Volume

Density of a penny = (Mass of the penny)/(Volume of the penny)

The density of a penny is approximately 7.14 g/cm³
