Astudent finds a piece of metal that she thinks is aluminum. she finds the volume to be 245 cm^3 and the mass to be 612 grams. is the metal aluminum? hint: find the density and show all work including units

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

The density of aluminium is 2.7 so we may conclude that the particular piece of metal found by the student is not aluminium.
