Happy Mole Day!

Happy Mole Day from our lab to yours!


Nice to mole you... meet you. Nice to meet you, Mole.” No, no, no.  Mole Day has nothing to do with Mike Myers or Austin Powers. It has everything to do with chemistry!

In honor of tradition, St. Thomas Aquinas High School chemistry students celebrated Mole Day, an annual recognition on October 23 of Avogadro’s Number (6.02 x 1023), which is a basic measuring unit in chemistry. Originally created as a way to foster interest in chemistry, Mole Day is used by STA in conjunction with various activities that promote chemistry and, well, moles.

For a given molecule, one mole is a mass (in grams) whose number is equal to the molar mass of the molecule. One mole of any substance contains Avogadro’s Number (AN) of molecules or atoms of that substance. This is where this author’s conceptual understanding dissolves other than to note that the AN was discovered and named for Amadeo Avogadro who received credit for the discovery after his death in 1858.

So happy Mole Day to chemistry lovers everywhere. And thank you, Ms. Nancy Hasbun, for inviting our Saints to the party.
