  1. How to do Stoichiometry By:Peter Greenawalt

  2. The Reaction • How many grams of Silicon Chloride and Water are needed to produce 7.25g of Hydrochloric acid? • SiCl4 + H2O  SiO2 + HCl

  3. Write a complete and balanced chemical equation SiCl4 + 2H2O  SiO2 + 4HCl

  4. Draw a column after each chemical SiCl4 + 2H2O  SiO2 + 4HCl

  5. Write the amount given in the correct columnSiCl4 + 2H2O  SiO2 + 4HCl

  6. Convert the amount given into MolesSiCl4 + 2H2O  SiO2 + 4HCl

  7. Find Moles for all the other Chemicalsa)In each of the other columns write moles given (x) as a fractionSiCl4 + 2H2O  SiO2 + 4HCl

  8. Find Moles for all the other Chemicalsb)the numerator of the fraction is the coefficient of the columnSiCl4 + 2H2O  SiO2 + 4HCl

  9. Find Moles for all the other Chemicalsc)the denominator of the fraction is the coefficient of the given columnSiCl4 + 2H2O  SiO2 + 4HCl

  10. Find Moles for all the other Chemicalsd) Do the math and label as molesSiCl4 + 2H2O  SiO2 + 4HCl

  11. Convert all Moles to GramsSiCl4 + 2H2O  SiO2 + 4HCl

  12. Verify the Law of Conservation of Mass(total mass of reactants=total mass of products) SiCl4 + 2H2O  SiO2 + 4HCl
