Blog Post 1: Describe 10nm and mole of atoms

MOLE of Atoms=
  -  6.02 X 10^23 carbon atoms.
  -  15 trillion earths
  -  The quantity of anything.  Any time you want to refer to a large number of things.  It's easier to say the unit "mole", than to write 6.02 x 10^23.
  -  Gives us a consistent method to convert between atoms/ molecules and grams. 
  -  Although it doesn't seem like it at first, once one becomes familiar with a mole, it will be as normal as a dozen or a byte.
  -  If you had a mole of pennies, you could give out enough money to everyone in the world so that they could spend a million dollars every hour, day and night, for the rest of their lives.
  -  If you had exactly one mole of sheets of paper, you could make one million equal stacks from sea level on the earth that would pass the sun.
  -  Given that the volume of a grain of sand is approximately 10-12 m3, and given that the area of the United States is about 1013m2, it therefore follows that a mole of sand grains would cover the United States in approximately one centimeter of sand.

10 NANOMETERS =
  - 1nm=10^ -9m    (reduced 1 billion meters)
  - 10nm= 10^ -8m (.000000001)
  - 100nm= 10^ -7m
  - 1,000nm= 10^ -6m     = 1mm

  -  size of a virus
  -  Size of a cell wall
  -  as a mm is to a km a nm is to a m
  -  10 nm = 10 nanometres = 10−8 metres
  -  10 nm — lower size of tobacco smoke
