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 simple mole ratio formula:

Where:

• \( n_a \) — Moles of substance A (mol)
• \( n_b \) — Moles of substance B (mol)

Explanation: The ratio represents how many moles of substance A exist per mole of substance B. It's dimensionless since both numerator and denominator are in the same units.

3. Importance of Mole Ratio

Details: Mole ratios are essential for balancing chemical equations, determining limiting reactants, and calculating theoretical yields in chemical reactions.

4. Using the Calculator

Tips: Enter the number of moles for both substances. The denominator (n_b) must be greater than zero. Values can be entered with up to 4 decimal places for precision.

5. Frequently Asked Questions (FAQ)

Q1: Can mole ratio be greater than 1?
A: Yes, the mole ratio can be any positive number. A ratio >1 means there are more moles of substance A than substance B.

Q2: How is mole ratio different from mass ratio?
A: Mole ratio compares the number of particles (moles), while mass ratio compares weights. They're only equal when molar masses are identical.

Q3: Where do I get the number of moles from?
A: Moles can be calculated from mass using the formula: moles = mass (g) / molar mass (g/mol).

Q4: Is mole ratio the same as coefficient ratio?
A: In balanced equations, the coefficient ratio equals the mole ratio of reactants and products.

Q5: What if my ratio is negative?
A: Mole ratios are always positive since you can't have negative moles. Check your input values.
