Key Features
Four specimens: copper, iron, zinc and aluminium
Each specimen contains approximately one mole of the element
Side-by-side comparison of mass and volume
Supports the concepts of the mole, mass and molar mass
About This Product
Placed side by side, the four specimens show that the same molar amount of each element has a different mass and occupies a different volume, because each element has its own atomic mass and density. Students can picture a mole of a substance in the solid state with this Molecular Model item and build their understanding of mass, molar mass and the differing properties of the metals.
Frequently Asked Questions
Q1. Why do the specimens differ if each is one mole? Each element has a different atomic mass and density, so the same molar amount has a different mass and occupies a different volume.
