The stoichiometry is the part of chemistry that studies the amounts of substances involved in the reactions. With stoichiometry you can know how the substances are before and how they will be after the chemical reaction.
All reactions depend on how many things they have. Stoichiometry helps you determine the amount or proportion of compounds that you will need in a chemical reaction.
Stoichiometry is present in daily life, even in the recipes we make at home.
The reactions depend on the compounds involved and how much of each compound is necessary, to determine the product that will result.
The elements that are taken into account in the stoichiometry are: mass of reactants (chemicals before the reaction); mass of products (chemicals after reaction); chemical equations; molecular weights of reagents and products and formulas of various compounds.

- Kitchen Recipes
Most people love cookies. In this case, stoichiometry helps us in the following way;
If you want to make 10 cookies, the chemical "equation" for the mass of reactants (chemicals before the reaction) would be:
200 grams of flour + 2 eggs + 200 grams of butter + 1 cup of sugar = 10 cookies.
But, it turns out that the reagent mass you have, or rather the ingredients, are incomplete because you only have one egg. A new chemical equation is made, where everything is cut in half to get a result:
100 grams of flour + 1 eggs + 100 grams of butter + 1/2 cup of sugar = 5 cookies.
The 5 cookies would be the mass of products (chemical products after the reaction), that is, the result of the union of the ingredients through a chemical equation.
- Car safety
Today automobiles are the main means of transportation for people anywhere in the world.
To make cars safer, car companies placed airbags on the steering wheel and other places inside the vehicle to protect people in the event of a crash.
With stoichiometry you can know how much nitrogen gas must be produced in a matter of seconds for the bag to inflate on impact, and can save the life of the driver or passengers.

Nowadays it is normal for people to locate themselves by their GPS to get an address or to know if you have a store or bank near them. This location system is made up of several satellites in space.
Stoichiometry helps calculate the fuel, weight, and materials needed for rockets to fly into space to put satellites in orbit. In addition, it calculates the fuel and reaction of the components of the orbiting satellite.
So we can enjoy a global positioning system so we don't get lost.
With these simple examples, you can see how daily life is filled with many more scientific elements than we know.
