What Are Some Mole Day Facts?

Mole Day is a day that is celebrated in commemoration of Avogadro's Number, which is a unit of measurement in chemistry applications. This number, which is 6.02 x 10 to the 23rd power, is celebrated annually between 6:02 a.m. and 6:02 p.m. on Oct. 23.

The official 2014 theme from the National Mole Day Foundation was "Mole-O'Ween." This theme was preceded by other themes such as "The Mole The Merrier," "It's a Mole World" and "Moles of the Round Table."

Originally the celebration of Mole Day was proposed in a small article by a high school chemistry teacher in the early 1980s. Mole Day was designed to bring people together to celebrate a day of chemistry and to help spread public awareness of the importance of the chemistry segment of the workforce.

Amadeo Avogadro is the man who developed Avogadro's number, which is equivalent to a mole. This finding was important as it marked an argument in favor of atoms and their presence. Avogadro's number is extremely large and is often measured out in examples of how many feet thick a layer of sand the size of Texas would be if each grain of sand represented a number in the equation. The answer is approximately 50 feet thick, which could cover an area of 262,000 square miles.
