Metal Density (g/cm3)

To determine the identity of the sample, we can calculate its density using the formula:

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

Given:

• Mass = 2.44 g
• Volume = 0.34 cm³

Let's calculate the density:

\[ \text{Density} = \frac{2.44 , \text{g}}{0.34 , \text{cm}^3} \approx 7.18 , \text{g/cm}^3 \]

Now, we can compare this density with the densities of the metals provided:

• Aluminum: 2.70 g/cm³
• Zinc: 7.14 g/cm³
• Iron: 7.87 g/cm³
• Copper: 8.96 g/cm³
• Silver: 10.49 g/cm³
• Lead: 11.34 g/cm³
• Mercury: 13.55 g/cm³
• Gold: 19.32 g/cm³

The calculated density of approximately 7.18 g/cm³ is closest to the density of zinc (7.14 g/cm³).

Therefore, the identity of the sample is: C. zinc
