It's time to party on National Mole Day, which falls on October 23! This day has been around since 1991 and celebrates Avogadro's Number (6.02x10^23), a fundamental measurement in chemistry. Celebrate by having a mole-themed party with your friends or family, complete with mole-shaped cookies and drinks! Whether you're an experienced chemist or someone who is just getting started in the field, National Mole Day is the perfect opportunity for everyone to get together and have some fun while learning about this important part of science.
