Counting Atoms in Reactions

Stoichiometry lets us calculate the exact amounts of reactants and products in a chemical reaction using balanced equations and molar ratios.

Steps to Success

1. Balance the chemical equation.
2. Convert quantities to moles.
3. Use mole ratios to find unknowns.
4. Convert back to grams or liters as needed.

Real-World Applications

• Baking: Recipes are like chemical equations; too much or too little of an ingredient changes the result.
• Industry: Manufacturing processes rely on precise chemical amounts to avoid waste.
