Unit 9 : Moles

• Mole


  A number that represents 6.02 x 10^23 particles (atoms, molecules, or formula units)
• A mole represents a much larger number than a dozen, specifically 6.02 x 10^23
• Mole

  Typically associated with a very small particle like an atom, molecule, or formula unit
• Avogadro's number

  6.02 x 10^23, the number of particles in one mole
• Converting moles to number of particles

  Multiply the number of moles by Avogadro's number
• Atoms


  The smallest unit of an element that still retains its properties
• Molecules


  Particles made up of multiple atoms of the same or different elements
• Formula units


  The smallest repeating unit of an ionic compound
• Converting moles of a compound to molecules/formula units

  Multiply the number of moles by Avogadro's number
• Converting moles to atoms

  Multiply the number of moles by Avogadro's number and then multiply by the number of atoms per molecule/formula unit
