Description
This set contains four element samples: aluminum, iron, copper, and zinc. Each sample has been sized to contain one mole of the element, or 6.022 x 1023 atoms. This number is called "Avogadro’s number". If you look up an element's atomic mass and measure out that many grams of the substance, you will have 6.022 x 1023 atoms, or one mole, of the element. The samples in this set make it easy to visualize a mole and allow students to practice physical measurements and mole calculations. The lab manual experiment uses the concept of a mole to identify the elements and estimate their atomic radii. The experiment is concluded with an application of specific heat for element identification. In addition to mole related experiments and demonstrations, there are a variety of other uses for this set, including density measurements, specific heat experiments, and examples of common elements.
