A mole is that furry little mammal that sticks its head out of dirt mounds. In Chemistry, a mole is Avogadro's number. Avogadro's number is the number of particles found in one mole of a substance. It is equal to 6.022 × 10^23. Therefore one mole of anything contains 6.022 × 10^23 atoms, formula units, ions, or molecules. Thus it depends on the nature of the substance. For example, one mole of carbon contains 6.022 × 10^23 atoms. Whereas one mole of water contains 6.022 × 10^23 molecules. Just like a dozen popcorn kernels is equal to 12 popcorn kernels. One mole of uncooked popcorn contains 6.022 × 10^23 popcorn kernels. As you can see, a mole is just a chemical quantity.

October 23 was also National Mole Day!

The Chemistry students choose an element from the Periodic Table to represent their hand made mole. Then they found the mass of their mole. The students used the mass of their mole and it's molar mass from the Periodic Table to determine how many atoms are inside their mole. Overall the students did a GREAT job! Below are just a few of the moles created by the Chemistry students. Can you tell which one is Thorium, Iron Mole, and Captain Americium?
