One Mole Carbon Block

Introducing our meticulously crafted 1 mole block of elemental carbon—a physical manifestation of the standardized unit of measure of a mole.

Dimensions: 1 x 1 x ~0.4” (25.4 x 25.4 x ~10.3 mm)
Mass: 12.011 g (± 0.08%)

What is a Mole?
A mole is a unit of measurement in chemistry used to express amounts of a chemical substance. It's defined as the amount containing as many entities (atoms, molecules, etc.) as there are atoms in 12 grams of pure Carbon-12. This quantity is known as Avogadro's number, 6.022 x 10²³.

Why 12.01 grams?
You might wonder why our block weighs 12.01 grams instead of the 12.00 grams one would expect from a mole of pure Carbon-12. This discrepancy arises from the presence of heavier isotopes in natural carbon. Unlike pure Carbon-12, which is tedious and expensive to isolate, natural elemental carbon includes traces of Carbon-13 and other isotopes. These contribute an additional 0.01 grams to the mass, offering an authentic representation of carbon as found in nature.

Our 1 mole block of elemental carbon is not just a curio—it's a tactile expression of fundamental scientific concepts, a conversation starter, and a thoughtful gift for anyone intrigued by the wonders of chemistry. Hold a mole in your hands, ponder the universe's intricacies, and add a touch of scientific intrigue to your life today!
