Answer 1

To calculate the density of iron, you can use the formula:

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

Given:
- Mass = 409.3 g
- Volume = 52.0 mL

Now plug in the values:

\[
\text{Density} = \frac{409.3 \, \text{g}}{52.0 \, \text{mL}} \approx 7.87 \, \text{g/mL}
\]

Therefore, the density of iron is approximately **7.87 g/mL**.
