1. What is the Mole Ratio Formula?

The mole ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. It's derived from the coefficients of a balanced chemical equation.

2. How Does the Calculator Work?

The calculator uses the mole ratio formula:

Where:

• \( \text{coeff}_a \) — Stoichiometric coefficient of substance A
• \( \text{coeff}_b \) — Stoichiometric coefficient of substance B

Explanation: The mole ratio shows the proportional relationship between reactants and products in a chemical reaction.

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 the coefficients come from?
A: Coefficients come from balancing the chemical equation for the reaction you're studying.

Q2: Can mole ratios be fractions?
A: Yes, mole ratios can be whole numbers or fractions depending on the balanced equation.

Q3: How is mole ratio different from mass ratio?
A: Mole ratio compares substance amounts in moles, while mass ratio compares their weights.

Q4: What if my equation has multiple reactants?
A: You can calculate multiple mole ratios between different pairs of substances.

Q5: Why must coefficient B be greater than zero?
A: Division by zero is mathematically undefined, so coefficient B cannot be zero.
