1. What is Mole Ratio in Chemistry?

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 Does the Calculator Work?

The calculator uses the mole ratio equation:

Where:

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

Explanation: The ratio represents how many moles of one substance react with or produce moles of another substance.

3. Importance of Mole Ratio

Details: Mole ratios are essential for stoichiometric calculations, determining limiting reactants, and predicting product amounts in chemical reactions.

4. Using the Calculator

Tips: Enter the coefficients from your balanced chemical equation. Coefficient B must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Where do I get the coefficients?
A: Coefficients come from balancing your chemical equation. For example, in 2H₂ + O₂ → 2H₂O, the H₂:O₂ ratio is 2:1.

Q2: Can mole ratio be less than 1?
A: Yes, when the denominator coefficient is larger than the numerator, the ratio will be less than 1.

Q3: How is mole ratio used in stoichiometry?
A: It converts between moles of different substances in a reaction. For example, moles A × (ratio B/A) = moles B.

Q4: Does mole ratio change with different units?
A: No, mole ratio is dimensionless and remains the same regardless of mass or volume units used.

Q5: What if my equation has fractions?
A: Multiply all coefficients by the denominator to eliminate fractions before calculating ratios.
