Step-by-step explanation:

It is given that,

Mass of the unknown substance, m = 13.5 gm

Volume of the substance,
$V=5\ cm^3$

We need to tell the unknown sample is made up of. It can be indicated using the density of the sample. It can be calculated as :

d=(m)/(V)

$d=(13.5\ gm)/(5\ cm^3)$

$d=2.7\ g/cm^3$

So, the density of the sample is
$2.7\ g/cm^3$ . The unknown sample is aluminium. Hence, this is the required solution.
