Mole: comparing different substances


This kit enables to compare quantities of different substances containing the same number of particles. Students can observe that the substances contained in the phials have the same number of particles (Avogadro’s number), but they have different masses and occupy different spaces. This situation is due to the following causes:
– different mass of molecules;
– different volume of molecules;
– different distances between the particles determined by cohesive forces.
