The Mole!!!
1 mole of anything = _______________________
­­Particles could be atoms, molecules, or beans!
­­Is it possible to count to a mole of beans??
If the world's population counted beans at a rate of 70 beans per minute for their entire lives (assume life expectancy of 71.4 yrs), how many beans would be counted?
(a mole is still 30,100 times bigger!)

(click here for a video overview of the mole concept)
­­a.k.a. "Avogadro's Number" ­­a word to represent a number, just like:
_________________________________
Molar Mass = The mass, in grams, of 1 mole of a substance...determine w/ the P.T.
6.02x1023 C atoms = 12.0g 6.02x1023 O atoms = 16.0g 1 mol CO2 molecules = 44.0g 2
