1. What is Mole Ratio?

The mole ratio compares the amounts in moles of any two compounds involved in a chemical reaction. It's a fundamental concept in stoichiometry used to predict reactant and product quantities.

2. How Does the Calculator Work?

The calculator uses the mole ratio equation:

Where:

• \( Moles\ A \) — Amount of substance A in moles
• \( Moles\ B \) — Amount of substance B in moles

Explanation: The ratio represents how many moles of one substance are present per mole of another substance.

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 moles of both substances (must be positive numbers). The calculator will compute their ratio.

5. Frequently Asked Questions (FAQ)

Q1: What units does mole ratio use?
A: Mole ratio is unitless as it's a ratio of two quantities with the same unit (moles).

Q2: How is mole ratio different from mass ratio?
A: Mole ratio compares substance amounts by particle count, while mass ratio compares by weight. Mole ratio is more useful in chemical calculations.

Q3: Where do I get mole values from?
A: Convert mass to moles using the substance's molar mass: moles = mass (g) / molar mass (g/mol).

Q4: 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.

Q5: How is mole ratio used in stoichiometry?
A: It's used to convert between quantities of reactants and products using balanced chemical equation coefficients.
