What is a mole?

Answer 1

Apart from a small furry animal, and a beauty mark, it is the `"chemists' dozen"`...

Explanation:

And `1*mol-=6.022xx10^23*"individual particles..."`

And thus the mole is the link between the sub-micro world of atoms and molecules, about which we theorize, and the macro world of grams, and kilograms, and litres, that which we can measure in a lab....

See here and links. Please be assured that this is a very important concept to grasp and understand....all of our ideas of chemical equivalence and mass balance depend on it.
