1. What is Mole Ratio in Chemistry?

The mole ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. It's used to determine the quantitative relationships between substances in chemical reactions.

2. How Does the Calculator Work?

The calculator uses the mole ratio formula:

Where:

• Moles A — Amount of substance A in moles
• Moles B — Amount of substance B in moles

Explanation: The mole ratio compares the quantities of two substances in a chemical reaction, which is fundamental for stoichiometric calculations.

3. Importance of Mole Ratio

Details: Mole ratios are essential for predicting product yields, determining limiting reactants, and balancing chemical equations in laboratory and industrial settings.

4. Using the Calculator

Tips: Enter the moles of both substances (must be positive numbers). The calculator will compute the ratio of substance A to substance B.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between mole ratio and mass ratio?
A: Mole ratio compares substance quantities in moles (particle counts), while mass ratio compares their weights. Mole ratio is more useful for chemical reactions.

Q2: 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.

Q3: What does a mole ratio of 2:1 mean?
A: It means there are 2 moles of substance A for every 1 mole of substance B in the reaction.

Q4: Can mole ratio be less than 1?
A: Yes, when substance A is present in smaller molar quantity than substance B, the ratio will be less than 1.

Q5: Why is mole ratio unitless?
A: Because it's a ratio of two quantities with the same unit (moles), the units cancel out.
