Chapter 7 Mole Concept and Stoichiometry

• Avogadro Constant


  • 6.02 x 10^23 particles for one mole
• Stoichiometry

  
• Stoichiometry

  
• Formulas

  
• Volumetric Analysis


  • involves the use of two solutions
  • analyte is the solution with unknown concentration
  • titrant is the solution with known solution
  • indicator is added to analyte in the conical flask before the titrant s added, the indicator changes colour when the titrant added has reacted completely with the analyte. (titration has reached the end point)
• Limiting reactant


  • the reactant that is completely used up in a reaction
  • amount of product formed depends on amount of limiting reactant
