Molar Eclipse of the Heart | Mole Day 2012

It’s Mole Day, everyone!

Only last week were we celebrating women in STEM thanks to Ada Lovelace Day. This week the science appreciation calendar let’s us unleash our inner chemistry fans and celebrate that wonderful unit of measurement, the MOLE!

It’s was all the way back in the 1800s that Amedeo Avogadro introduced us to the handy unit, and today it remains a vital tool for scientists.

In the name of Mole Day our team has been working on a musical treat for the many Avogadro fans around the world.

Without further a do, Molar Eclipse of the Heart!

(Given the catchy nature of the number, we’ve included the lyrics below.)

Underground, moles are little animals with really weird noses who like to dig around

Round and brown, every here and there you’ll find a hairy brown spot on your skin, we also call that a mole!

Search around, moles are spies who work in private espionage, they spy in secret, and they don’t make a sound

Also found,
Everywhere in mexico Mole is a spicy sauce
Same spelling but a whole different sound!

Turnaround blind eyes
Don’t you know it’s more than you can tell

Turnaround blind eyes, moles can also mean something else
‘Cos in chemistry a mole.
Is a unit used to measure,
The atoms or molecules,
In a substance of whatever!
It’s the number of carbon twelve atoms
In twelve grams of carbon…
Matter’s filled with way too many atoms to count,
So use Avagadro’s number to express the amount!

For any type of matter: solid, liquid or gas,
The grams within a mole will equal atomic mass.
All you need is a mole!

Six-oh-two sextillion!
Six-oh-two sextillion!

Six point oh two two, one four oh seven eight,
Times 10 to power of twenty three
That number’s a mole
We use it in chemistry.

Once upon a time Avagadro said hey!
And showed us the way out of the dark,
His number you must use,
A molar eclipse of the heart.

A molar eclipse of the heart.
