International Mole Day 2017

Hi there,

Welcome to International Mole Day wherever you are in the world!!

Today is the 23rd October 2017 and it is International Mole Day.

That’s 10.23.17.

On International Mole Day we celebrate all that is the Mole, that’s not the furry, little critters who bury under your lawn but the massive number sometimes called Avogadro's Number with the symbol L.

It is 6.0223 ×10²³ particles or any thing else for that matter that's a really big number of things.

602,000,000,000,000,000,000,000 things actually.

So why not have a day to celebrate this vast quantity of stuff.

This number of atoms of carbon weigh 12.00000g if the carbon atom is a carbon-12 isotope.

This number of grams is the atomic mass of carbon and its the standard atomic mass against which all other masses of atoms are measured.

So a mole of magnesium atoms weigh 24.000g.

A mole of helium atoms weigh 4.000g.

There are four posts I've put up to show how you can use the mole in your chemistry.

You can find them here, and here, and here, and here.

Look them over on this blog.

To celebrate today here are some images:

and don't forget Mole Time which is 6.02pm on 10.23.17!!
