Good morning NOPErs and welcome to Mole Day... well between 6.02am and 6.02pm it is Mole Day... now you might think this has something to do with those blind little rat things known to breed just so they can have a food source during winter, yep they eat their young, but NOPE.... Mole Day is one for the nerds, chem nerds that is... Mole Day celebrates Avogadro’s Number (6.02 x 1023). Huh???... well for those who didn't do chem or who slept through chem or who left school and never thought of chem and periodic tables again... a MOL is a unit of measure in chemistry, it is how one measures the mass of a molecule. Its really important to know this if you are wanting to make things that go boom.... or pass your end of year chemistry exam... For a given molecule, one mole is a mass (in grams) whose number is equal to the atomic mass of the molecule. For example, the water molecule has an atomic mass of 18, therefore one mole of water weighs 18 grams. An atom of neon has an atomic mass of 20, therefore one mole of neon weighs 20 grams. In general, one mole of any substance contains Avogadro’s Number of molecules or atoms of that substance. This relationship was first discovered by Amadeo Avogadro (1776-1858) and he received credit for this after his death. So thank you Amadeo for coming up with your special number... it was so much for fun 6 months of my life... never to be thought of again until now.

 

Starting your day with conveluted chemisty constructs or starting it with a smoke.... Both are a

NOPE .... cos even in chem speak its still has power.

About us

QuitTrain®, a quit smoking support community, was created by former smokers who have a deep desire to help people quit smoking and to help keep those quits intact.  This place should be a safe haven to escape the daily grind and focus on protecting our quits.  We don't believe that there is a "one size fits all" approach when it comes to quitting smoking.  Each of us has our own unique set of circumstances which contributes to how we go about quitting and more importantly, how we keep our quits.
