1. A furry, quite cute (to some) animal that lives in burrows.
2. An spy in the enemy's camp (infiltrator/rat)
3. A black, raised discolouration on the skin

Hope that helped  :D
And for the chemical definition u can look it up in any chemistry book. Or google it, about a thousand pages'll come up.

Avogardo's constant : 6 x 10^23

Mole number : mass / relative molecular mass, volume x concentration, dm^3 / 24
