One-Mole Metal Bar Set, 4 Elements

This mole set includes 4 metal bars that each represent one mole of the respective element. The bars allow students to physically hold and compare one mole of different metals, making the abstract concept of the mole tangible and concrete. By comparing the weight and size of bars that each contain Avogadro's number of atoms, students develop an intuitive understanding of molar mass and its relationship to atomic mass. Suitable for chemistry classrooms studying stoichiometry and the mole concept.
