Today is Mole Day! This isn't small cylindrical mammal appreciation day, it's a day to commemorate a basic unit in chemistry. A mole is defined as the number equal to the number of carbon atoms in exactly 12 grams of pure carbon-12. What is that number? It's 6.02214179 x 10^{23 }and is commonly referred to as Avogadro's Number, after the 19th century scientist Amedeo Avogadro.

If you had a mole of M&Ms, you'd have 6.02214179 x 10^{23 }M&Ms - plenty of M&Ms to get through all 12 seasons of Murder, She Wrote. Now, if you had a mole of dollars...

You could pay off the US national debt and not notice the difference...

1 mole of dollars: $602,214,179,000,000,000,000,000

US national debt: $19,739,152,000,000*

If you spent a billion dollars a second, it would take you over 19 million years to spend a mole of dollars.

A mole is a big number. A big number routinely used to quantify tiny things like atoms, compounds, or molecules. We can fit a mole of some well-known elements into petri dishes...

It looks like there are different amounts of each element present. There are AND there are not. Image having a mole of Dachshund and a mole of Great Danes. You'd have ~6.02 x 10^{23 }of each dog, but your mole of Dachshunds and your mole of Great Danes would take up different amounts of space and have different masses.

A mole is like a chemist's version of a dozen. Now imagine if you had a mole of donuts.... nomnomnom

[...] As Rooke points out, this calculation is easily done using the information provided (i.e. loss of gold is 3.66 g - 3.49 g = 0.17 g), the atomic weight of gold (Au), and Avogadro's number. [...]

I prefer Mole Day the Mexican delicious sauce.
