1. What is Theoretical Mole Ratio?

The theoretical mole ratio is the ratio of coefficients of two substances in a balanced chemical equation. It represents the ideal proportion in which reactants combine or products form according to the stoichiometry of the reaction.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Coeff A} \) — Stoichiometric coefficient of substance A
• \( \text{Coeff B} \) — Stoichiometric coefficient of substance B

Explanation: The ratio is derived directly from the balanced chemical equation and represents the mole-to-mole relationship between the two substances.

3. Importance of Theoretical Ratio

Details: The theoretical ratio is crucial for predicting reaction yields, determining limiting reactants, and calculating expected product quantities in chemical reactions.

4. Using the Calculator

Tips: Enter the coefficients from your balanced chemical equation. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: How is this different from actual mole ratio?
A: Theoretical ratio comes from the equation, while actual ratio comes from experimental measurements and may differ due to side reactions or incomplete reactions.

Q2: Can coefficients be fractions?
A: Yes, some balanced equations use fractional coefficients to maintain whole number ratios of atoms.

Q3: What if my ratio is greater than 1?
A: A ratio >1 means there are more moles of substance A per mole of substance B in the equation.

Q4: How does this relate to limiting reactants?
A: Comparing actual and theoretical ratios helps identify which reactant is limiting in a real reaction.

Q5: Can this be used for any chemical equation?
A: Yes, as long as the equation is properly balanced, this ratio calculation applies.
