Oct. 23rd is Mole Day

WHY is Oct. 23rd Mole Day you ask?

Avogadro figured out long ago that there are 6.02 x 10 to the 23 power atoms in one atomic mass unit of every element (i.e. look at Carbon on the Periodic Table. It's atomic mass is 12. So in 12 grams of carbon there are 6.02 x 10 to the 23 power atoms of carbon atoms in 12 grams. It works for every element. It makes conversion between elements very easy.).

SO on Oct (10th month) 23 (GET IT??) (10 to the 23rd??) we celebrate mole day.
Well, officially only at 6:02 AM or PM (I forget which).

And I just KNOW all my readers wanted to know this!

I still remember my highschool chemistry teacher introducing us to the mole--he drew a picture on the board complete with big digging paws and whiskers!

BEAKER!!!! He's been my favorite Muppet ever since I can remember. Anyway, I also wanted to let you know that you've officially been TAGGED!

(By the way, you're also an enabler of my #7 fact.) Whenever I get a new SHS digest, I always look for the political articles that you've posted. THANK YOU and PLEASE keep it up!!!!
