	Sunday, October 23, 2005 ::FUN CHEMISTRY FACT OF THE DAY, PART 8:: Someone googled the phrase "happy mole day poem" to find this blog a few days ago. This makes me squealy with... well, squeals. It's Mole Day. That means the date and time were Avogadro's number, about 6.02 x 10²³ (602,000,000,000,000,000,000,000). Today's 10-23. Get it? A mole of a substance equals Avogadro's number of atoms of a substance. It's stoichiometrically useful. So, not to disappoint, I give you a "happy mole day poem": What's that on your face? Hair from a brown bump erupts Avogadro smiles - Summer, 7:28 PM Comments: That's amazing! is a chemist Heh. # posted by Anonymous : 10:28 PM Q. What do you get if you cut an avocado (sic, perhaps?) into 6.02x10^23 pieces? ...Summer, you should totally get this.

For example one mole of peanuts is 6.022x10^23 peanuts, or for a quantity of a chemical, 6.022x10^23 molecules. # posted by the oxtopus : 8:27 AM Yeah, you're right about the definition. But there's no "happens to be" in that bit about the mole of C-12 being 12 grams. That's the actual definition, I think, and it's really hard to put into words. # posted by Summer : 8:59 AM Post a Comment
