6.02 x 1023
Avogadro’s Number
SI unit for measuring the amount of a substance
# of atoms in 12 grams of pure Carbon-12

1 mol of water = 18 ml
1mol of pennies = stack the pennies – the stack could reach to the sun and back 2 billion times
1 mol of dollars = could not all be spent even if you spent a billion dollars a day over a trillion years
1 mol paperclips – could wrap around the world 400 trillion times

The mass in grams of one mole of any pure substance is called its “molar mass”
Molar mass of any element equals its atomic mass
Unit = g/mol
Ex. 1 mol Fe = grams
1 mol NaCl = =
