blog post 1: describe 10 nm and mole of atoms

The size of 10nm is equivalent to the thickness of a cell wall and the diameter of a virus cell.  The diameter of an insulin molecule is actually 5nm, so two of those could be equivalent to it as well.  In other words, the size of 10nm is extremely small.

A mole on the other hand, is the complete opposite.  Imagine the amount of ocean water there is on planet Earth.  That number amount is actually 3.586 * 10^20 gallons of water.  A mole is equal to 6.02 * 10^23.  If we took the Earth and multiplied it by 100, the amount of water we would have would be ALMOST equal to a mole.  In fact it would still slightly be smaller than a mole of atoms.  In other words, the size of a mole of atoms is extremely large.
