What happens at 6:02 on 10/23? Can't figure it out? It's mole day!
Mole day is celebrated from 6:02am-6:02pm on October 23 to commemorate Avogadro's number: 6.02x1023 (get it?). I'm sure the chemistry-lovers out there already know this, but to clarify: Avogadro determined that one mole of any given substance contains 6.02x1023 particles.
So, to celebrate, get crazy--drink one mole of water (18g or 0.63 ounces) at 6:02am!
*Don't worry, it's still the 22nd. We just wanted to prepare you for tomorrow.
