1. What is Mole Ratio?

The mole ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. It's a fundamental concept in stoichiometry that helps determine the quantitative relationships between reactants and products in chemical reactions.

2. How Does the Calculator Work?

The calculator uses the mole ratio formula:

Where:

• \( n_A \) — Moles of substance A
• \( n_B \) — Moles of substance B

Explanation: The mole ratio compares the number of moles of one substance to another in a chemical reaction or compound.

3. Importance of Mole Ratio

Details: Mole ratios are essential for:

• Balancing chemical equations
• Determining limiting reactants
• Calculating theoretical yields
• Converting between amounts of reactants and products

4. Using the Calculator

Tips: Enter the number of moles for both substances. The calculator will compute their ratio. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between mole ratio and mass ratio?
A: Mole ratio compares the number of particles (moles), while mass ratio compares weights. Mole ratio is more useful in chemical reactions as it relates directly to particle counts.

Q2: How do I find moles from grams?
A: Use the formula: moles = mass (g) / molar mass (g/mol). You'll need to know the substance's molar mass.

Q3: Can mole ratio be less than 1?
A: Yes, when the numerator substance has fewer moles than the denominator substance.

Q4: How is mole ratio used in stoichiometry?
A: It's used to convert between quantities of reactants and products using the coefficients from balanced chemical equations.

Q5: What does a mole ratio of 2:1 mean?
A: It means there are 2 moles of the first substance for every 1 mole of the second substance in the reaction or compound.
