1. STOICHIOMETRY How can I use stoichiometry to calculate reactant and product amounts?

2. What is the mole ratio of smores? Where do mole ratios come from? 2 Gc + 1 M + 4 Cp  1 Smore

3. Molar Ratios … help to relate quantities of reactants to products. are derived from a balanced equation. adhere to the Law of Conservation of Matter. Bread : Ham 2: 1

4. Converting Mass to Mass Problems Use Road Map Provided Follow Directions – like following a recipe!

5. Ex. WHAT MASS OF CARBON IS REQUIRED TO REACT WITH OXYGEN TO PRODUCE 12g OF CO? _____ C + ______ O 2  ______ CO 2 12 Circle the known. Box what you are trying to find. GIVEN 12 g CO g CO mol CO C: 1 x 12 = 12 O: 1 x 16 = 16 + 28 g/ mol 28 1 mol CO mol C 2 2 g C C: 1 x 12 = 12 g/ mol 1 12 = 5.14 g C
