What is stoichiometry

Stoichiometry is a branch of chemistry that deals with the quantitative relationships that exist among the reactants and products in chemical reactions. To put it simply, it's the math behind chemistry.

Here are the steps to understand stoichiometry:

1. Understand the Mole Concept: Stoichiometry is based on the law of conservation of mass where the total mass of the reactants equals the total mass of the products leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers.

2. Understand the Balanced Chemical Equation: The coefficients in a balanced chemical equation shows how many moles of one reactant are needed to react with other reactants and how many moles of product will be formed.

3. Molar Mass: It is the mass of 1 mole of a substance. It is used to convert moles of a substance to grams or grams of a substance to moles.

4. Mole Ratio: It is the ratio of moles of one substance to the moles of another substance in a balanced equation.

5. Using these concepts, you can calculate the amount of reactants needed or product produced in a chemical reaction.

Remember, stoichiometry involves making calculations based on chemical reactions, so it's important to understand how to balance chemical equations and know how to use conversion factors to convert between different units of measurement.
