To calculate the density of the substance, you can use the formula:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
Given that the mass is 4725 grams and the volume is 350 cm³, we can substitute the values:
\[ \text{Density} = \frac{4725 , \text{grams}}{350 , \text{cm}^3} \approx 13.5 , \text{g/cm}^3 \]
Now, we can compare this density to those of the substances provided:
- Gold: 19.32 g/cm³
- Lead: 11.34 g/cm³
- Iron: 7.87 g/cm³
- Mercury: 13.56 g/cm³
The calculated density of approximately 13.5 g/cm³ closely matches that of Mercury (13.56 g/cm³).
Therefore, the substance identified is Mercury.
