Answer:
The metal is Aluminium
Explanation:
To answer this question we need to find the density of the element.
The density will help us identify the metal.
Formula for getting density is given by :
Density = mass/volume
Mass = 13.5 grams
Volume = 5 cm³
Doing the substitution we have :
Density = 13.5/5 = 2.7 grams/cm³
We need to identify a metal with a density of 2.7g/cm³
From the list of metals and their densities the metal that has a density of 2.7 g/cm³ is Aluminium.
The correct identity of the metal is Aluminium.
