Answer:
D. 1kg Aluminium
Explanation:
First of all, you have to know that you were given two quantities, volume and mass.
The relationship between both quantities is given by the formula of density which is:
Density = Mass / Volume
Volume = Mass / Density
Since mass is constant, it means that the volume is inversely proportional to the density.
Volume = k / Density where k is a constant.
This means that the substance with the lowest density would have the highest volume and the one with the highest density would have the highest lowest.
The density of the substances are given as:
Lead = 11.2
Iron = 7.874
Gold = 19.3
Aluminium = 2.7
This means that Aluminium would have the highest volume as its the least dense.
