Nakamura One-Mole Substances

A set of one-mole units of four substances: copper (Cu), iron (Fe), aluminum (Al), and Carbon (C). The four cylinders have the same diameter and are produced using a number of grams of each substance equivalent to the atomic mass of the substance (e.g., 63.5g of copper, atomic mass: 63.5). Thus, they can be used to concretely confirm the Avogadro's number of each atom, 6.2 x 1023, for observation purposes.

It is also possible to compare the weights of one mole of various substances.

Note: This set is particularly useful for specific heat experiments.
