Answer : Aluminium.
Explanation : To find the correct answer we can find out the density of the sample,
Using the density formula which is,
Density ρ = [tex] \frac{mass (m)}{volume (v)} [/tex]
Here, Mass = 13.5 g; Volume = 5 [tex] cm^{3}[/tex]
on calculating we get,
Density = [tex] \frac{13.5}{5} = 2.7 g/cm^{3}[/tex]
Which shows that, aluminum has this density. Aluminum has density as [tex] 2.7 g/cm^{3}[/tex]
So, the correct answer will be aluminum.
