Mole Day – Celebrate It Today

Mole Day

If you like to celebrate somewhat offbeat and quirky celebrations, then Mole Day is undoubtedly for you. So what exactly is Mole Day? If you’re thinking of those furry creatures that can make a real mess of your lawn, you’re on the wrong track. Equally we’re not discussing unsightly markings on the skin.

The National Mole Day Foundation, Inc. would love to tell you what it’s really all about. Here is the explanation from their website:

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.

So away you go. Why not call up all your friends and have a Mole Day party? .. or invite a Chemist to lunch.
