To find the mass of a piece of aluminum given its volume and density, you can use the formula:
\[
\text{Mass} = \text{Density} \times \text{Volume}
\]
In this case, the density of aluminum is 2.7 g/cm³ and the volume is 12.5 cm³.
Now, we can calculate:
\[
\text{Mass} = 2.7 \, \text{g/cm}^3 \times 12.5 \, \text{cm}^3
\]
\[
\text{Mass} = 33.75 \, \text{g}
\]
So, the mass of a 12.5 cm³ piece of aluminum is **33.75 g**.
\[
\text{Mass} = \text{Density} \times \text{Volume}
\]
In this case, the density of aluminum is 2.7 g/cm³ and the volume is 12.5 cm³.
Now, we can calculate:
\[
\text{Mass} = 2.7 \, \text{g/cm}^3 \times 12.5 \, \text{cm}^3
\]
\[
\text{Mass} = 33.75 \, \text{g}
\]
So, the mass of a 12.5 cm³ piece of aluminum is **33.75 g**.
