Stoichiometry Summary

  1. Write a guide to solving a stoichiometry problem with moles.
    For example, calculate moles of CO2 made when 3.4 moles of butane (C4H10) are burned, using this chemical equation:
    2C4H10 + 13O2 → 8CO2 + 10H2O
  2. Write a guide to solving a stoichiometry problem with grams.
    For example, calculate grams of O2 used up when 125 grams of butane (C4H10) are burned, using this chemical equation:
    2C4H10 + 13O2 → 8CO2 + 10H2O
  3. Write a guide to solving a limiting reactant stoichiometry problem with grams.
    For example, calculate grams of H2O made when 125 grams of butane (C4H10) are reacted with 550 grams of oxygen (O2), using this chemical equation:
    2C4H10 + 13O2 → 8CO2 + 10H2O
  4. Write a guide to solving a limiting reactant stoichiometry problem with grams.
    For example, calculate grams of O2 left over when 89 grams of butane (C4H10) are reacted with 475 grams of oxygen (O2). Oxygen is the excess reactant in this problem set-up.
    2C4H10 + 13O2 → 8CO2 + 10H2O
