    Happy National Mole Day! Find out what Mole Day is, and what it has to do with math (think chemistry), in this post from Mathnasium, the math learning center!

    Happy National Mole Day!!

    Never heard of it before? Don't worry. Mole Day doesn't get as much attention as Pi Day, but in math and chemistry circles, October 23rd is a great day to celebrate numbers!

    Today we recognize Amadeo Avogadro's Number (6.02 x 1023), which is a basic unit of measurement in chemistry. 

    "For a given molecule, one mole is a mass (in grams) whose number is equal to the molar mass of the molecule. For example, the water molecule has an molar mass of 18, therefore one mole of water weighs 18 grams. Similarly, a mole of neon has a molar mass of 20 grams. In general, one mole of any substance contains Avogadro's Number of molecules or atoms of that substance." (from the National Mole Day Foundation website.)

    What are some things you can do to celebrate Mole Day? Here are some ideas:

    • Draw moles on small pieces of paper and hand them out saying "Happy Mole Day!"
    • Make a molecule out of toothpicks and marshmallows.
    • Make a sculpture of a mole out of clay, fabric, paper, etc. and put it in a place of honor for the day.
    • Write your own mole joke and tell it to your family and friends.

    Regardless of whether or not you're a chemistry fan, it's always fun to celebrate these special days. Whether you're using one of our ideas above, or coming up with your own creative commemoration, tell us in the comments how YOU are celebrating Mole day!

    Before I came to Mathnasium, I could sum up everything I felt about math in one word: 'EVIL!' I hated math. ... Mathnasium has been my safe haven. They truly have shown me the light when it came to addressing my fear and provided me with the tools that I need to rebuild my prior knowledge so that I won't forget it. Math is no longer a subject I shy away from but it is a subject I can boldly accept and understand.
