International Mole Day 23 October 2021: History, Detail

Every year, on October 23rd, Mole Day is observed. Mole Day honors Avogadro's Number, which is a fundamental measuring unit in chemistry. This day was designed to pique people's interest in chemistry. To define the number of particles present in a single mole of any substance, the Avogadro number is denoted as 6.021023. This number, also known as a mole, was discovered by Amedeo Avogadro, an 18th-century Italian scientist, as a basic measuring unit for atoms and molecules.

History Of The Day 

The Ideal day began in the 1980s when an article appeared in The Science Teacher. Maurice Oehler, a retired high school chemistry teacher from Wisconsin, USA, was inspired by the article and founded the National Mole Day Foundation.

In American format, the day resembles the Avogadro number, which represents the number of molecules or atoms contained in a mole.

International Mole Day is a special day for everyone who is involved with the subject of chemistry. To commemorate this day, many molecular and chemistry-related activities are held.
