To identify the unknown substance based on its mass (56.5 grams), you need to calculate its density. The density can be calculated using the formula:
\[ \text{Density} = \frac{\text{mass}}{\text{volume}} \]
However, to determine the identity of the substance, the density would need to be compared to the known densities of the materials listed (aluminum, gold, iron, and lead).
Here are the approximate densities for the substances you've mentioned:
- **Aluminum**: ~2.7 g/cm³
- **Gold**: ~19.3 g/cm³
- **Iron**: ~7.9 g/cm³
- **Lead**: ~11.3 g/cm³
If you can provide the volume of the unknown substance, I can compute the density. Once we have the density, we can accurately compare it to the densities of the materials listed to identify the unknown substance.
\[ \text{Density} = \frac{\text{mass}}{\text{volume}} \]
