To identify an unknown metal based on its mass and volume, we first need to calculate its density. The density of a substance is given by the formula:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
Given the mass and volume:
- Mass (\( m \)) = 0.968 kg (which is 968 grams, since 1 kg = 1000 g)
- Volume (\( V \)) = 123 cm³
Now, we can calculate the density:
\[ \text{Density} = \frac{968 \text{ g}}{123 \text{ cm}³} \approx 7.87 \text{ g/cm}³ \]
Next, we can compare this density to the densities of common metals to identify the most likely candidate:
- Iron (Fe): about 7.87 g/cm³
- Nickel (Ni): about 8.90 g/cm³
- Copper (Cu): about 8.96 g/cm³
- Zinc (Zn): about 7.14 g/cm³
- Tin (Sn): about 7.31 g/cm³
The calculated density of approximately 7.87 g/cm³ closely matches that of iron. Therefore, the unknown metal is most likely iron.
