To calculate the mass of the aluminum piece, you can use the formula:
\[
\text{Mass} = \text{Density} \times \text{Volume}
\]
Given:
- Density of aluminum = 2.7 g/cm³
- Volume = 12.5 cm³
Now, substituting the values into the formula:
\[
\text{Mass} = 2.7 \ \text{g/cm}^3 \times 12.5 \ \text{cm}^3 = 33.75 \ \text{g}
\]
Therefore, the mass of the 12.5 cm³ piece of aluminum is **33.75 g**.
