How to perform stoichiometry calculations

Stoichiometry is a branch of chemistry that deals with calculating the amounts of reactants and products in chemical reactions. To perform stoichiometry calculations, follow these steps:

1. Write a balanced chemical equation for the reaction.

2. Identify the substances involved in the reaction (reactants and products).

3. Convert the given quantity of one substance (usually a reactant) into moles using its molar mass. This can be done using the formula: moles = mass / molar mass.

4. Use the coefficients in the balanced equation to determine the mole ratio between the given substance and the substance you want to find the quantity of.

5. Calculate the quantity of the desired substance in moles using the mole ratio determined in step 4.

6. Convert the quantity of the desired substance from moles to grams (if necessary) using its molar mass.

7. Check your answer to ensure it makes sense in the context of the problem and the original chemical equation.

By following these steps, you can perform stoichiometry calculations to determine the quantities of reactants and products in a chemical reaction.
