The Stoichiometry calculator is an online tool used in chemistry to instantly calculate the quantitative relationship that exists between the quantities of reactants and products involved in a balanced chemical reaction.
What is Stoichiometry in Chemistry?
In Chemistry,
“The relationship between the relative quantities of substances taking part in a chemical reaction before, during, and following the reaction”
The word 'stoichiometry' comes from the Greek words “stoicheion”, meaning element, and “metron”, meaning measure.
Types of Stoichiometry:
In chemistry, stoichiometry primarily has three main types:
1. Reaction Stoichiometry:
This type deals with the quantitative relationship between reactants and products in a chemical reaction. It focuses on balancing chemical equations and determining the exact amounts of reactants needed and products produced based on the balanced equation.
The Reaction Stoichiometric further classified into four categories:
- Mass to mass stoichiometry
- Mass-to-mole conversion
- Mole to mass steps conversion
- Mole to mole stoichiometry
2. Composition Stoichiometry:
Composition stoichiometry involves calculating the composition of compounds in terms of the elements they contain. It helps determine the mass or moles of each element present in a compound, given its chemical formula.
3. Gaseous Stoichiometry:
Gaseous stoichiometry pertains to reactions involving gases. It often involves using the ideal gas law to relate quantities of gases in reactions. This type of stoichiometry is particularly important in industries like gas production and environmental monitoring.
How to Calculate Reaction Stoichiometry?
To calculate stoichiometry, you have to understand some factors that directly depend on what type of chemical reaction is going to happen.
Examples:
Here we have several types of stoichiometry problems on the basis of measurements that are utilized for the reactants involved in moles, mass, and volume.
Stoichiometry Calculations Between Mole-Mole:
As sulfur reacts with oxygen, it produces sulfur trioxide, which is represented by the equation below.
2S + 3O2= 2SO3 is a stoichiometry formula.
Calculation of the Mass-Molecule:
Potassium chlorate breaks down to produce oxygen as shown in the following stoichiometry equations.
O2 + 2KClO3= 2KCl + 3O2
Conversions Between Volume and Moles Stoichiometry:
When ammonia and hydrogen react it produces hydrogen, as shown in the equation.
2NH3 is formed via the reaction of N2 with 3H2.
Working of Stoichiometry Calculator:
The working of the stoichiometry calculator is straightforward. You need to put an equation to stoichiometry solver and get the final result such as
What to do:
- Enter the chemical equation you want to calculate into their designated field.
- you can load the pre-saved example reaction.
- Tap the Calculate Button.
What you get:
- The amount of reactants and products in moles and grams.
FAQs:
What is another name for stoichiometry?
Stoichiometry means figuring out how much stuff you need and how much stuff you'll make when chemicals react. It's like a math for chemistry. Another word to say stoichiometry is chemical arithmetic, reaction calculation, and mole ratio calculations.
What are stoichiometry applications in the real world?
Stoichiometry is used in various fields in the real world such as in fireworks manufacturing, and engineering work, and also used by pharmaceutical companies.
