How big is a mole chemistry fun facts?
An eastern mole (Scalopus aquaticus) weighs about 75 grams, which means a mole of moles weighs (6.022×10^23)×75g≈4.52×10^22kg. That’s a little over half the mass of our moon. Mammals are largely water.

Can we cover the earth with one mole of pennies?
However, a mole of pennies would cover the Earth at a depth of over 400 metres. And a mole of moles would weigh over half the size of the moon!
Why is a mole 6.022 x10 23?
The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×1023elementary entities of the substance.
