1. What is Actual Yield?

Actual yield is the amount of product actually obtained from a chemical reaction, as opposed to the theoretical yield which is the maximum possible amount. It's typically expressed in grams and is often less than the theoretical yield due to practical limitations.

2. How Does the Calculator Work?

The calculator uses the actual yield formula:

Where:

• \( \text{Actual} \) — Actual yield in grams
• \( \text{Yield} \) — Percentage yield (0-100%)
• \( \text{Theoretical} \) — Theoretical yield in grams

Explanation: The formula converts the percentage yield into the actual mass obtained by scaling the theoretical yield.

3. Importance of Actual Yield Calculation

Details: Calculating actual yield helps chemists assess reaction efficiency, optimize processes, and determine economic viability of chemical processes.

4. Using the Calculator

Tips: Enter percentage yield (0-100%) and theoretical yield in grams. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is actual yield less than theoretical yield?
A: Actual yield is often lower due to incomplete reactions, side reactions, product loss during purification, and practical limitations.

Q2: What is a good percentage yield?
A: In research, 50-70% is often acceptable, while industrial processes aim for 90%+. However, this varies by reaction type.

Q3: How can I improve my actual yield?
A: Optimize reaction conditions, use pure reagents, minimize side reactions, and improve isolation techniques.

Q4: What's the difference between actual yield and percent yield?
A: Actual yield is the mass obtained, while percent yield is (actual/theoretical)×100, showing efficiency.

Q5: Can actual yield ever exceed theoretical yield?
A: Normally no, unless the product contains impurities that increase mass or theoretical yield was miscalculated.
