Avogadro’s Number. 6.02x10 23. mole = (mol) 602000000000000000000000. Mole. A mole is just a number like… Pair = 2 Trio = 3 Dozen = 12 Baker’s dozen = 13 Gross = 144 Score= 20 Century=100 Ream=500. How BIG is a mole?. There are ~ 6.6 billion people on Earth
Pair = 2 Trio = 3
Dozen = 12 Baker’s dozen = 13
Gross = 144 Score= 20
There are ~ 6.6 billion people on Earth
How many Earths would it take to equal the population
of 1 mole?
9.12 x 1013
2.06 x 109 years
They would create a sphere
Water molecules are so small
that a mole of H2O = 18ml
THAT’s WHERE THE
MOLE COMES IN!

1 mol C atoms = 6.02 x 10 23 C atoms = 12g C
inGram Formula MassGram Molecular Mass Molar Mass
1 mole of NaCl = 58g = 6.02x1023 particles of NaCl
1 mole of H2O = 18g = 6.02x1023 molecules of H20
Use factor label & follow the units!
