Answer:
The piece of metal found by the student is not aluminium.
Explanation:
First we calculate the density using the following formula:
density = mass (g) / volume (cm³)
Now the density of the metal piece:
density = 612 g / 245 cm³ = 2.49 [tex]\frac{g}{cm^{3}}[/tex]
The density of aluminium is 2.7 [tex]\frac{g}{cm^{3}}[/tex] so we may conclude that the particular piece of metal found by the student is not aluminium.
