What is an example of a stoichiometry practice problem?
A stoichiometry problem would entail using a balanced chemical equation and mole and mass conversion factors in an attempt to
calculate the amounts of substances involved in a chemical reaction.
Let's take a basic example of a mass to mass stoichiometry problem.
Nitrogen gas and hydrogen gas are combined to form ammonia. What mass of ammonia can be produced from a 10.00 gram sample of nitrogen is combined with an excess of oxygen.
First we must write out a balanced chemical reaction for the process.
Next we must determine what is known and what we want to find.
Now we create a roadmap for the process.
Then we find the molar mass of the substances.
We follow up with the conversion factors for each change of unit.
Calculate the value and cancel the units.
