What is Mole day? Mole day is an event to celebrate science using chemistry as the star of the show, leading us to other disciplines.
What is a Mole? A mole is a number used for counting things, like a dozen is used for counting eggs. A mole is a much bigger number though, 6.02 times 10 to the 23. That means 602,000,000,000,000,000,000,000 or 602 sextillion of something. We need a big number because we're counting molecules. Have a look at the pictures below and find the special box that contains one mole of air. You need a big big number to count molecules until you can see something and hold it in your hand. That's what we use the mole for. It's a way to measure out a certain amount of molecules for reactions.
