To determine the unknown metal, you can calculate its density using the formula:
\[
\text{Density} = \frac{\text{Mass}}{\text{Volume}}
\]
In this case, you have a mass of 17.8 g and a volume of 2 cm³:
\[
\text{Density} = \frac{17.8 \, \text{g}}{2 \, \text{cm}^3} = 8.9 \, \text{g/cm}^3
\]
Next, you can compare the calculated density of 8.9 g/cm³ to the densities of known metals. Common metals and their densities include:
- Aluminum: 2.7 g/cm³
- Copper: 8.96 g/cm³
- Iron: 7.87 g/cm³
- Lead: 11.34 g/cm³
- Silver: 10.49 g/cm³
- Gold: 19.32 g/cm³
From this list, the density of the unknown metal (8.9 g/cm³) closely matches that of copper (approximately 8.96 g/cm³). Therefore, the unknown metal is likely to be copper.
