Mole Day

Mole Day

Mole Day is October 23rd and it is a celebration of the mole. Not the animal or the skin growth. Mole Day celebrates a unit of measurement.

A mole is the amount of a substance that contains as many particles as there are atoms in 12 grams of carbon-12. Moles are important in chemistry because they allow chemists to measure quantities of substances very precisely.

Mole Day was created by the National Chemistry Week Committee in 1991. The day was chosen because Avogadro's Number (6.02 x 10^23) is similar to October 23rd (10/23). Mole Day is celebrated by chemists and chemistry students all over the world. There are many ways to celebrate, but common activities include mole-themed parties, eating mole-shaped cookies, and wearing mole-themed clothing.

Mole Day is a great way to get students interested in chemistry. It's also a great opportunity to learn about moles and how they are used in chemistry. So celebrate Mole Day and learn something new about the moles unit of measurement!
