To identify the unknown substance, we need to calculate its density using the formula:

\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]

However, you haven't provided the volume of the substance placed in the graduated cylinder. The mass is given as 56.5 grams.

To determine the identity of the unknown substance, we can compare the calculated density (once we have the volume) with the known densities of the materials listed:

- **Aluminum**: Approximately 2.7 g/cm³
- **Gold**: Approximately 19.3 g/cm³
- **Iron**: Approximately 7.9 g/cm³
- **Lead**: Approximately 11.3 g/cm³

If you can provide the volume of the substance, we can calculate its density and then identify which material it matches based on standard densities.
