Stoichiometry Tutorial Stoichiometry is a very important topic in chemistry, one which will critical for your understanding of many topics for a number of different chemistry courses in your future! Stoichiometric problems allow you to calculate the amounts (mass) of reactants and products that will be consumed or produced during a chemical reaction. A typical stoichiometric problem would be: What mass of water will be produced if 18.5 grams of hydrogen gas react with excess oxygen gas? (when you see the word “excess” in a problem like this it implies that there is more than enough oxygen to complete the reaction, meaning that the hydrogen is the limiting reactant). The first thing (always) you will require to complete a stoichiometric problem is a BALANCED EQUATION. By this point in your chemistry education you should be able to convert the above sentence into a chemical equation. (H 2 + O 2 b H 2 O)… …and then balance it to: 2H 2 + O 2 b 2H 2 O OK! We’re off to a good start… but what is this balanced equation actually telling us? It tells us the
