- coefficients in balanced equations tell us the number of mole reacted or produced - they can also be used as conversion factors
  3X + Y --> 2Z

Examples:
- How many moles of Iron Fluoride are required to produced 2.7mol of pure Iron?
2Fe
F₃ --> 2Fe + 3F_{2 2.7mol x 2/2 = 2.7mol}                                                                                                                                                                                                                                                                                                                                                           -When 3.8mol of Magnesium reacts with Lithium Iodide. How many mole of Magnesium should be produced?                                                                                                                                                                  Mg + 2LiI --> 2Li + MgI2 - How many moles of Potassium Nitride are required to produced 8.5mol of pure Potassium?
