1. What is Mole Ratio?

The mole ratio compares the amounts in moles of any two compounds involved in a chemical reaction. It's derived from the coefficients in a balanced chemical equation and used in stoichiometric calculations.

2. How Does the Calculator Work?

The calculator uses the mole ratio formula:

Where:

• \( Experimental\ Moles\ A \) — Moles of substance A
• \( Moles\ B \) — Moles of substance B

Explanation: The ratio compares the experimental moles of substance A to the moles of substance B, showing their proportional relationship.

3. Importance of Mole Ratio

Details: Mole ratios are fundamental in stoichiometry for predicting reactant requirements, product yields, and understanding reaction proportions.

4. Using the Calculator

Tips: Enter moles of substance A and substance B. Both values must be positive numbers. The calculator will compute their ratio.

5. Frequently Asked Questions (FAQ)

Q1: How is mole ratio different from mass ratio?
A: Mole ratio compares substance amounts in moles (particle counts), while mass ratio compares their weights. Mole ratio is more chemically meaningful.

Q2: What's the theoretical vs experimental mole ratio?
A: Theoretical comes from balanced equations; experimental comes from actual measurements. Comparing them helps assess reaction efficiency.

Q3: Can mole ratio be less than 1?
A: Yes, when there are fewer moles of substance A than substance B in the ratio A:B.

Q4: How does mole ratio relate to limiting reactants?
A: The reactant with the smallest mole ratio (actual/theoretical) is the limiting reactant.

Q5: Why use moles instead of grams?
A: Moles account for different molecular weights, allowing direct comparison of particle numbers in reactions.
