Mole Day is celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m. It celebrates Avogadro’s Number (6.02 x 1023), which is a basic measuring unit in chemistry. Mole Day was created as a way to foster interest in chemistry, and schools throughout the United States and around the world celebrate with various activities related to chemistry and/or moles.

For a given molecule, one mole is a mass (in grams) whose number is equal to the atomic mass of the molecule. For example, the water molecule has an atomic mass of 18, therefore one mole of water weighs 18 grams. An atom of neon has an atomic mass of 20, therefore one mole of neon weighs 20 grams. In general, one mole of any substance contains Avogadro’s Number of molecules or atoms of that substance. This relationship was first discovered by Amadeo Avogadro (1776-1858) and he received credit for this after his death.

History of Mole Day

The days was established by the Mole Day foundation to be celebrated on Oct 23rd from 6:02am to 6:02pm, commemorating thea forementioned Avogardo’s Number (6.02 x 1023). The purpose of the day was to help encourage people to take an active interest in chemistry, and to alert people of the interesting facts surrounding the mole unit.

How to Celebrate Mole Day

You can start your celebration by reading up on the hypothetical question of “What if one had a mole of moles?” We’ll warn you ahead of time that this description gets a bit complex and almost certainly gruesome. Consider it your scientifically accurate horror story for Halloween.

You can also create Mole themed art, focusing on the idea that every molecule has its own mole number, representing the weight of a mole of a given molecule. Water has a mole number of 18 grams, for instance, while neon has a molar mass of 20 grams.

The animal that shares the same name is the unofficial mascot of Mole Day, and one of the most popular ways of Celebrating Mole Day is by creating Mole themed plushie mascots and built designs that represent that Mole.
