Today is October 23rd; 10-23.

If you’re involved in any way with the field of chemistry, 10 to the power 23 should ring a bell – Avogadro’s constant, 6.02 x 10^23, the number of particles in a ‘mole’ of a substance, is a basic quantity in chemistry.  To quote wikipedia:
“The mole is a unit of measurement used in chemistry to express amounts of a chemical substance, defined as an amount of a substance that contains as many elementary entities (e.g., atoms, molecules, ions, electrons) as there are atoms in 12 grams of pure carbon-12, the isotope of carbon with atomic weight 12. This corresponds to a value of 6.02214179×10^23 elementary entities of the substance. It is one of the base units in the International System of Units, and has the unit symbol mol.”

In celebration of the above, Mole Day is celebrated on October 23rd, from 6:02 am to 6:02 pm. Generally the day involves activities that represent puns on ‘mole’ or ‘avogadro’. For 2012, the official theme for Mole Day is ‘Molar Eclipse’.

Mole Day was created to foster an interest in chemistry.

So how do you celebrate this day? Well, you can go on a molercoaster ride, or make a meal with avogadro dip or guaca-mole sauce. Have a Rock ‘n’ Mole party. Whatever you do, involve as many of your friends as possible – the mole the merrier! 🙂

I’m sure readers of this blog will be able to come up with many funnier, punnier activities to engage in on Mole Day – any suggestions?

  1. I know nothing about chemistry (and am too tired to think of a pun), but I love books. One of my favourite books tells me that Avogadro’s constant is a big enough number that “the equivalent in soft drink cans would, evenly stacked, cover the earth to a depth of two hundred miles”.
