  • KIT CONTENTS || This kit contains samples of four different metals. Each piece consists of one mole of that element (copper, iron, zinc, and aluminum)
  • MOLAR MASS || A mole measures the amount of a substance in a sample. It is defined as the amount of a chemical substance that contains as many units (e.g., atoms of an element, molecules of a compound, electrons, protons, ions, or what have you…) as there are atoms in 12 grams of carbon-12.
  • BAR MEASUREMENTS || Zinc: 2.3" x 0.5" x 0.5". Aluminum 2.5" x 0.5" x 0.5". Iron 1.8" x 0.5" x 0.5". Copper 1.8" x 0.5" x 0.5"


The set of 4 metal bars (Copper, Iron, Zinc, and Aluminum) each represent one mole. This is a great way to represent the abstract concept of mole and molar mass in a visually and kinesthetically effective way.
Bar measurements:
(A) 2.3" W x 0.5" L x 0.5"H
(B) 2.5" W x 0.5" L x 0.5"H
(C) 1.8"W x 0.5" L x 0.5"H
(D) 1.8" W x 0.5" L x 0.5"H

The quality of these is great, and they come with a sturdy little plastic box. It's great that they are not labelled with what they are, so it can be a sort of mystery. One easy solution without doing any measurements is to use a magnet, and then the others are obvious.This set is not ideal for doing density by weight-in-the-hand, since each piece is a different size.

The weights are very close to the reference table accepted masses.
