Happy Mole Day, one and all!

Today is Mole Day! Celebrated by chemists from 6.02 am to 6.02 pm on October 23rd, Mole Day commemorates Avogadro’s number (6.022 x 1023), which is the number of atoms in exactly 12 grams of carbon-12 (one mole). This was founded by the National Mole Day Foundation on 15th May 1991.

Mole Day is what happened On This Day in Chemistry. We have a selection of resources about moles, including a quiz on our Wiki as well as an Assessment for Learning activity to on calculations, a Gridlocks game and an experiment on how to calculate the volume of one mole of hydrogen at room temperature and pressure. There is also a resource pack for teaching Gifted and Talented students about Avogadro's number and other astounding numbers.

What do you do to help students understand what a mole is?
