1. What is Mole Ratio?

The mole ratio is the ratio of coefficients of substances in a balanced chemical equation. It shows the proportional relationship between reactants and products in a chemical reaction.

2. How to Calculate Mole Ratio

The calculator uses the mole ratio formula:

Where:

• \( \text{coeff}_a \) — Coefficient of substance A in the balanced equation
• \( \text{coeff}_b \) — Coefficient of substance B in the balanced equation

Explanation: The mole ratio is derived directly from the coefficients in a balanced chemical equation and is used for stoichiometric calculations.

3. Importance of Mole Ratio

Details: Mole ratios are essential for predicting amounts of reactants needed or products formed in chemical reactions, and for converting between different substances in a reaction.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Can mole ratio be less than 1?
A: Yes, when the coefficient in the numerator is smaller than the denominator.

Q2: How is mole ratio different from mass ratio?
A: Mole ratio compares substance amounts in moles, while mass ratio compares their weights.

Q3: Can mole ratio be used for any substances in an equation?
A: Yes, between any two substances (reactant-reactant, reactant-product, or product-product).

Q4: What if my chemical equation isn't balanced?
A: You must balance the equation first to get correct coefficients for mole ratio calculations.

Q5: Are mole ratios always whole numbers?
A: In simple equations yes, but some complex reactions may have fractional coefficients.
