The mole set helps students visualize a mole in solid state. It contains four element specimens: Copper, Iron, Zinc and Aluminium. Each sample contains one mole, 6.02 x 1023 atoms of the element. This will help students develop a greater understanding of the concept of the mole, mass, molar mass, as well as a greater knowledge of the properties of each element when they compare these four specimens side by side.
