If 29.4 grams of hydrogen and 3701.3 grams of iodine combine to form hydrogen iodide, how many grams of hydrogen iodide must form?
First write down a balanced chemical equation for the reaction :
This represents the mole ratio in which chemicals combine.
Now calculate the number of moles of each reactant present :
Since the balanced chemical equation illustrates that the reactants combine in a
So hence, since
This corresponds to a mass of product of
