Mole...

A mole is the unit of measurement one uses when measuring atoms, ions and molecules. Mole is used because using grams or any other normal measurement would be impractical and it wouldn’t work very well at all whereas mole was designed to measure molecules, atoms and ions.

Mole is, if you want to get technical, 6.02 x 10 to the power of 23 – Avogadro’s number. Most times though people just refer to this quite big number as ‘mole’.

I believe that this was a good site to have a look at about mole, as it didn’t go into all the chemistry jargon, it was short, it was simple and it was understandable. There was not much there to confuse you and it was fairly easy to make sense of.
