This Mole Set contains samples of four different metals and helps students to visualise mole of substance in solid state, as well as developing better understanding of the concept of the mole, mass, molar mass, along with the differing properties of the various metals. The set contains four element specimens: copper, iron, zinc and aluminium, each containing approximately one mole (6.023 1023 atoms) of the element. Comparison of each sample, side-by-side, clearly shows that the same molar amount of different elements have different masses and occupy different volumes, due to each element having different atomic mass and density.
