What Is Mole Day?Avogadro's number is the number of particles in a mole of a substance. Mole Day is an unofficial chemistry holiday celebrated on a date that relates to Avogadro's number, which is approximately 6.02 x 1023. The purpose of Mole Day is to foster an interest in chemistry.
When Is Mole Day?In the US this is usually October 23rd between 6:02 am and 6:02 pm. (6:02 10/23). The dates for National Chemistry Week actually are chosen so that Mole Day falls within Mole Week. Alternate observance dates for Mole Day are June 2 (6/02 in MM-DD format) and February 6 (6/02 in DD-MM format) from 10:23 am to 10:23 pm.
Mole Day ActivitiesWhenever you choose to celebrate it, Mole Day is a great day to think about chemistry in general and the mole in particular. Here are some Mole Day activities for you:
- Determine how much aluminum foil you would need to make a 0.5 mole aluminum sculpture (of a mole, if you like). Weigh out the foil and get creative.
- Write your own mole joke. Examples of mole jokes include:
Where did Avogadro stay on is vacation? A mole-tel.
What do chemists wear when it's cold? Ther-mole underwear.
- Make up a song about the mole. You should get bonus points if you make a video and upload it to YouTube.
- Determine how much water is in one mole of water. Can you drink that amount?
- Experimentally determine Avogadro's number.
