1. What is Reaction Stoichiometry?

Stoichiometry is the calculation of relative quantities of reactants and products in chemical reactions. It is based on the conservation of mass and the concept of moles.

2. How Does the Calculator Work?

The calculator uses the stoichiometry equation:

Where:

• \( n_{\text{product}} \) — Amount of product (mol)
• \( n_{\text{reactant}} \) — Amount of reactant (mol)
• \( \text{coeff}_{\text{product}} \) — Stoichiometric coefficient of product
• \( \text{coeff}_{\text{reactant}} \) — Stoichiometric coefficient of reactant

Explanation: The equation shows the mole ratio between reactants and products in a balanced chemical equation.

3. Importance of Stoichiometric Calculations

Details: Stoichiometry is essential for predicting product yields, determining limiting reagents, and ensuring proper reactant ratios in chemical reactions.

4. Using the Calculator

Tips: Enter the amount of reactant in moles and the stoichiometric coefficients for both reactant and product. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are stoichiometric coefficients?
A: These are the numbers before chemical formulas in a balanced equation, showing the mole ratios of substances in the reaction.

Q2: Why is the mole concept important in stoichiometry?
A: Moles allow chemists to count particles by weighing them, making it possible to relate masses of different substances in a reaction.

Q3: What is a limiting reactant?
A: The reactant that is completely consumed first, determining the maximum amount of product that can be formed.

Q4: How does stoichiometry relate to the law of conservation of mass?
A: Stoichiometry calculations ensure that mass is conserved - the total mass of reactants equals the total mass of products.

Q5: Can this calculator be used for gas stoichiometry?
A: Yes, as long as amounts are in moles. For gas volumes at STP, remember that 1 mole = 22.4 L.
