About the Mole Zone
Not quite the small mammal that lives underground, a mole is a unit of measurement used to measure the number atoms or molecules. We can actually measure anything in moles, but it’s not very useful for most things because the numbers are so big…
One mole of something is equal to Avogrado’s number: 6.02×1023 or 602,000,000,000,000,000,000,000 – it’s not easy to say this number in words! To help you imagine how big this is, there are about this number of human cells on Earth. If you were to count out this number of coins at a rate of one coin per second, it would take you twenty thousand million million years to finish…it’s an extremely large number!
This is a general engineering zone, where you will meet engineers working in a range of areas.
