A student 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. Calculate the density of metals. Is the metal aluminum?

Answer:

Density = 2.5 g/cm³ , The metal is aluminium.

Step-by-step explanation:

Density is defined as the ratio of the mass and the volume

Thus,


Density=\frac {Mass}{Volume}

Given that:

Mass = 612 grams

Volume = 245 cm³

Thus, Density is:


Density=\frac {612}{245}\ g/cm^3

Density = 2.5 g/cm³

Metals are shiny with high density.

The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range.

The metal is aluminium.
