National Mole Day! 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 10^23), which is a basic measuring unit in chemistry. 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. 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. The theme for Mole day 2011 will be: Moles of the Round Tables MOLE PLEDGE (Background: When saying the pledge of allegiance to the U.S. flag, one faces the flag. If no flag is present, one should face our nation's capitol, Washington D.C. When saying the pledge to the mole, a real mole is usually not present. So, one should bend over and face the earth!) "I pledge allegiance to the mole, and to the science from which it comes, one SI unit, extremely divisible, with micromoles and millimoles for all. I pledge allegiance to the mole, to the International Union of Pure and Applied Chemistry, and to the atomic mass for which it stands, one number, most divisible, with atoms and molecules for all." Everything you ever wanted to know about moles but were afraid to ask (and much you didn't want to know) Words with mole: demoleition - The destruction which moles bring about in your yard. dismole - being gloomy on Mole Day imoleble -
