October 23 - Mole Day -- Principles of Chemistry
What is Mole Day?
Celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m., Mole Day commemorates Avogadro's Number (6.02 x 1023)
which is a basic measuring unit in chemistry. In other words, if you have a mole of something, you have 602,000,000,000,000,000,000,000 of that object. This amount is so large because chemists work with atoms and molecules which are incredibly small. A mole is sometimes called "a chemist's dozen".
Mole Day was created as a way to foster interest in chemistry. Schools throughout the United States and around the world celebrate Mole Day with various activities related to chemistry and/or moles.
602,000,000,000,000,000,000,000 is also refer to as "Avogadro's number". It is Amedeo Avogadro's (1776-1858) initial research paved the way for later scientists to use this amount to be able to measure quantities of tiny objects like atoms and molecules.
