Mole Set
Product Code : EL-MM-11011
Quick answer: The Mole Set is a teaching set of four metal specimens, copper, iron, zinc and aluminium, each containing about one mole of the element, roughly 6.02 x 10^23 atoms. Placed side by side, the samples show that one mole of different elements has a different mass and volume, making the mole concept and molar mass concrete. Lab Exports manufactures it in Delhi for schools, colleges and universities.
Specifications
| Parameter | Value |
|---|---|
| Elements | Copper, iron, zinc, aluminium |
| Quantity per sample | Approximately 1 mole |
| Atoms per sample | About 6.02 x 10^23 (Avogadro constant) |
How the set is used in teaching
The mole is the chemist's counting unit: one mole of any substance contains the Avogadro number of particles, about 6.02 x 10^23. The mass of one mole, the molar mass, equals the relative atomic mass in grams, so one mole of aluminium has a mass of about 27 g, iron about 55.8 g, copper about 63.5 g and zinc about 65.4 g.
Each sample in the set contains roughly that amount, so students are looking at the same number of atoms four times over. The aluminium sample is the lightest of the four yet has the largest volume of metal, because aluminium atoms are light and the metal has a low density.
- Weigh each sample, allowing for any container, and compare the mass with the molar mass from the periodic table.
- Work out the number of moles in each as mass divided by molar mass; each should come out close to 1.
- Multiply by the Avogadro constant to estimate the number of atoms in each sample.
- Discuss why equal numbers of atoms give different masses and volumes for the four metals.

Frequently asked questions
How much of each metal is in the Mole Set?
Approximately one mole of each, about 6.02 x 10^23 atoms. By molar mass that is roughly 63.5 g of copper, 55.8 g of iron, 65.4 g of zinc and 27 g of aluminium.
Why do the one-mole samples differ in size?
Each contains the same number of atoms, but the metals differ in atomic mass and density, so one mole of each has a different mass and occupies a different volume.
