Unitless dimensions - Pi Avogadro Coulomb

Unitless dimensions are typically used to refer to # of things

• 1 mole (AKA avogadro’s constant) = some number but typically used to say 1 mole of molecules
  • 1 mole of cakes = 6.022 * 10²³ cakes
  • 1 mole of molecules = 6.022 * 10²³ molecules
• 1 Coulomb = some number but typically used to say 1 colomb of electrons
  • 1 Coulomb of cakes = 1.036 * 10^-5 cakes
  • 1 Coulomb of electrons = 1.036 * 10^-5 electrons
• 1 pi = 3.14
