Stoichiometry Calculator- Formulas, Problems, Applications

In Chemistry, you will often come across the term ‘Stoichiometry’. It is one of the most important topics that you need to study and one of the most challenging ones too!

A chemical reaction occurs when compounds or substances undergo a chemical change to form various compounds or substances. These equations express chemical reactions in terms of symbols and chemical formulas of the compounds involved in reactions.

Stoichiometry Calculator


Stoichiometry deals with the study of the relationship between the number of moles of the reactants and the products in a chemical reaction. It relies on the Law of conservation of mass. The law of conservation of mass states that, in a chemical reaction, the amount of reactants is equal to the number of products formed. This follows from the math’s principle that states, “Matter can neither be created nor be destroyed. It can only be converted from one form to another”.

Therefore, the relation between the number of reactants and products is a ratio of positive integers.

Stoichiometry Chemistry

Stoichiometry states that the amount of any particular element on the reactant side of the equation should be equal to the amount of that element on the product side.

For example, in the equation:

2 H2 + O2 –> 2H2O,

Since there are two molecules of hydrogen on the reactants’ side, there should also be 2 hydrogen molecules on the products’ side.

As we have discussed earlier, stoichiometry calculations act based on the ‘Law of conservation of mass.’

Thus, it follows the principle that the amount of an element on the reactants’ side will be equal to the amount of the element on the products’ side.

Stoichiometry Calculator online

Although the calculations can be a bit tough for many people, the stoichiometry calculator is making it easier. Stoichiometry calculator is an online tool that can be used with a lot of ease. So, you can use it to make all types of calculations regarding stoichiometry.

Stoichiometry calculator Chemistry

You need to follow these set of rules to make calculations using the stoichiometry calculator. Hence, read these rules carefully:

Step 1: Firstly, type the chemical equation for which you need to find the stoichiometric values. Do this in the ‘Input a reaction Equation’ box. Now, there can be two types of solving requirements.

Either the number of moles of the reactants in the equation might be provided. Or on the other hand, the number of moles of the products in the equation might be given.

Step 2: Secondly, you have to choose among the given options. The two provided         options are: ‘Reactant amount given’ or ‘Product amount given’. You will choose the   one for which you know the values.

Step 3: Thirdly, corresponding to the names of the reactants or products, you have to fill in  the amount of the elements present. This amount can be expressed in four different forms. They are moles, grams, liters (liquid), or liters (gas).

Step 4: After filling in all the required details, directly click on the ‘calculate’ button.

Finally, the result is displayed.

Here, the output is displayed in a proper format.

  • Firstly, the first table will display the initial amount of the reactants present (in grams as well as moles).
  • Secondly, the next table displays the unreacted amount of reactants in the equation.
  • Thirdly, the last table will finally display the number of products produced in the process.

Thus, this solves the question in totality.

You can use the following calculator to make correct stoichiometric calculations every single time:


Stoichiometry calculator uses

You can use the stoichiometry calculator for a multiple reasons. They are as follows:

  • The calculator provides almost correct results.
  • The stoichiometry calculator is pretty easily available.
  • Therefore, it is not at all time-consuming, as compared to the pen and paper based method.
  • Also, you do not need to know the stoichiometry formula for using the stoichiometry calculator. Thus, you just need to know either the number of moles of reactants. Or the number of moles of products formed in the process. As you can see, using this calculator is a simple process. So, people can widely use it all over the world.
