NATIONAL MOLE DAY – October 23

NATIONAL MOLE DAY

You may be thinking that this day is in honor of the little burrowing creature however, it is not.  National Mole Day is celebrated by chemists and chemistry students  each year on the 23rd of October,

This celebration takes place between 6:02 AM and 6:02 PM, making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from Avogadro’s number, which is approximately 6.02×10^23, defining the number of particles (atoms or molecules) in one mole of substance, one of the seven base SI units.

  • Mole is a unit of measurement used in chemistry to express amounts of a chemical substance.
  • Avogadro’s number, is a historical term closely related to the Avogadro constant.
  • The Avogadro constant is named after the early 19th century Italian scientist Amedeo Avogadro.
