Stoichiometry Calculator - An Introduction
The stoichiometry solver is used for the determination of concentration between reactants and products. An online stoichiometry ratio calculator automatically resolves your issues regarding the concentrations.
The stoichiometry reaction calculator is a beneficial tool for students, researchers, professionals, or anyone who needs it.
Definition of Stoichiometry:
The word “stoichiometry” emerged from the Greek words. Stoikein and metron, where “stoikhein” means element, and “metron” means measure. So stoichiometry means measuring elements. In chemistry, stoichiometry describes the quantitative relationship between reactants and products in a chemical reaction.
While doing stoichiometry calculations, the law of conservation of mass and the law of definite proportions must be obeyed as the mass of reactants is equal to the mass of the products in the chemical reaction.
Types of Stoichiometry observed:
During stoichiometric reactions, different types of relationships are observed. Below are some relationships that are generally viewed and can be studied using the balanced chemical equation. If you want to balance a chemical equation you can use our chemical equation balancer.
Mass-mass Relationship:
If the mass of one substance is known then the mass of the other substance can be found using this relationship. The mass of the substance can also be found online using our atomic mass finder.
Mass-mole Relationship:
This is also known as the mole-mass relationship. If the mass of one substance is known then we can find the moles of the other substance. Or if the moles of the substance are known then we can find the mass of the other substance.
Mass-volume Relationship:
In mass-volume relationships, if the mass of one substance is known then we can find the volume of the other substance.
Related: The mass of substances is in grams sometimes and its important to measure in moles so you can utilize our converter for grams to moles for such conversions.
What are Stoichiometric coefficients?
Stoichiometry coefficients are used to balance a chemical equation. It is the number written in front of elements or molecules of each side of the reactants and the products to balance a chemical equation.
Furthermore, Balancing a chemical equation is a hard task to do. You can use our Chemical equation solver to balance chemical equations.
How to solve Stoichiometry problems using our stoichiometry solver?
Stoichiometry problems can be solved using our stoichiometry calculator but sometimes you have to find it manually. We give describe two examples to help you find out how to do it manually,
Example 1:
14 grams of KOH reacted with an excess of H2SO4. Find the number of grams of K2SO4 and water that is produced as a result.
Solution:
Mass of KOH = 14 grams
The Molar mass of KOH = 39 + 16 + 1 = 56g/mol
Number of moles of KOH = 14/56 = 0.25 mol
We can write the equation of this chemical reaction as,
2KOH + H2SO4 → K2SO4 + 2H2O
To find the number of moles we will compare KOH with K2SO4.
KOH: K2SO4
2: 1
1: ½
0.25: 0.125
Therefore, about 0.125 moles of K2SO4 is being produced from 0.25 moles of KOH.
The Molar mass of K2SO4 = 2 * 39 + 96
We will get 174 g/mol
Now we will find the mass of KOH that is produced. For that, we will multiply the number of moles by the molar mass
0.125 * 174
21.75grams
To find the molecular mass of K2SO4 use our Molecular mass calculator.
Example 2:
Magnesium metal reacts with HCl giving hydrogen gas. Calculate the minimum volume of HCl solution which is 27% by weight and it is required to produce 12.1 grams of H2. Its equation is given as Mg + 2HCl → MgCl2 + H2
Solution:
Mass of H2 = 12.1 g
The molar mass of H2 = 2.016 (as there are 2 hydrogen atoms)
The Moles of Hydrogen (H2) = mass of H2 / molar mass of H2
Moles of H2 = 12 / 2.016 = 6 moles
Comparing the number of moles of H2 with HCl
H2 : HCl
1: 2
6: 12
So, there are 12 moles of HCl to produce 6 moles of H2.
The Mass of hydrochloric acid is equivalent to = moles of HCl * molar mass of HCl
12 * 36.5 = 438 g
The weight of HCl is 27% means that 27 g of HCl in HCl solution = 100g
1g of HCl in HCl solution = 100 / 27
438 g of HCl in the HCl solution = 100/27 * 438
1622.22g
For finding the concentration of HCl use our molal concentration calculator.
