1. What is Theoretical Mole Ratio Percentage?

The Theoretical Mole Ratio Percentage compares the actual mole ratio obtained in an experiment to the theoretical mole ratio predicted by stoichiometry. It measures how close your experimental results are to the expected values.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Actual \) — The experimentally obtained mole ratio (unitless)
• \( Theoretical \) — The expected mole ratio from stoichiometry (unitless)

Explanation: This calculation shows what percentage of the theoretical yield was actually achieved in the experiment.

3. Importance of Mole Ratio Calculation

Details: Calculating mole ratio percentages helps assess reaction efficiency, identify side reactions, and evaluate experimental technique. It's crucial for yield optimization and process improvement.

4. Using the Calculator

Tips: Enter both actual and theoretical mole ratios as unitless values. Both values must be positive numbers. The result shows the percentage of the theoretical ratio achieved.

5. Frequently Asked Questions (FAQ)

Q1: What does a percentage over 100% mean?
A: Values >100% suggest impurities, measurement errors, or incomplete product isolation.

Q2: What's considered a good percentage?
A: Typically 90-110% is acceptable, but this varies by experiment. Consult your procedure for specific expectations.

Q3: Why is my percentage very low?
A: Low percentages may indicate incomplete reactions, side reactions, or product loss during workup.

Q4: Can I use this for limiting reagent calculations?
A: Yes, this can help determine which reactant is limiting based on actual vs. theoretical ratios.

Q5: How precise should my measurements be?
A: Use at least 3-4 significant figures for meaningful percentage calculations.
