THE MOLE/AVAGADROS NUMBER

  • 1 Mole = 6.02 × 1023 objects

  • Amedeo Avagadro decided 6.02 × 1023 molecules per mole

  • Allows us to use periodic table to find atomic mass units or grams

  • If there are multiple atoms in a molecule, add individual masses to find the molar mass

  • When converting from moles, can find “molecules”, or “particles"(more generic), or atoms
