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 comes from the coefficients of a balanced chemical equation and is used in stoichiometric calculations.

2. How Does the Calculator Work?

The calculator uses the mole ratio equation:

Where:

• \( \text{Coefficient A} \) — Stoichiometric coefficient of first compound (dimensionless)
• \( \text{Coefficient B} \) — Stoichiometric coefficient of second compound (dimensionless)

Explanation: The ratio represents how many moles of one substance react with or are produced from another substance in a balanced chemical equation.

3. Importance of Mole Ratio

Details: Mole ratios are essential for predicting amounts of reactants needed or products formed in chemical reactions. They form the basis for stoichiometric calculations in chemistry.

4. Using the Calculator

Tips: Enter the coefficients from your balanced chemical equation. Coefficient B must be greater than zero. The result is a dimensionless ratio.

5. Frequently Asked Questions (FAQ)

Q1: Can the mole ratio be less than 1?
A: Yes, if the coefficient of the first substance is smaller than the second substance in the balanced equation.

Q2: How is mole ratio different from mass ratio?
A: Mole ratio compares number of particles (moles), while mass ratio compares weights. They differ because substances have different molar masses.

Q3: Where do I get the coefficients for the calculation?
A: The coefficients come from a properly balanced chemical equation for the reaction you're studying.

Q4: Can I use this for ionic equations?
A: Yes, as long as you're using the coefficients from the balanced net ionic equation.

Q5: What if my equation has fractions as coefficients?
A: You can use fractional coefficients, though it's often preferable to multiply all coefficients by the denominator to get whole numbers.
