Yield Formula:
| From: | To: |
Yield calculation is a fundamental concept in chemistry and manufacturing that measures the efficiency of a process. It compares the actual amount of product obtained to the maximum theoretical amount that could be produced under ideal conditions.
The calculator uses the yield formula:
Where:
Explanation: The formula calculates what percentage of the theoretically possible product was actually obtained in the process.
Details: Yield calculation is crucial for evaluating process efficiency, identifying areas for improvement, calculating production costs, and ensuring quality control in chemical reactions and manufacturing processes.
Tips: Enter both actual and theoretical values in grams. Ensure both values are positive numbers. The calculator will automatically compute the yield percentage.
Q1: What is considered a good yield percentage?
A: This varies by industry and process, but generally yields above 90% are considered excellent, while yields below 60% may indicate significant inefficiencies.
Q2: Why might actual yield be less than theoretical yield?
A: Common reasons include incomplete reactions, side reactions, product loss during purification, measurement errors, and imperfect reaction conditions.
Q3: Can yield exceed 100%?
A: In theory, no. If yield calculations show more than 100%, it typically indicates measurement errors, impure products, or incorrect theoretical yield calculations.
Q4: How is theoretical yield determined?
A: Theoretical yield is calculated based on stoichiometry of the balanced chemical equation, using the limiting reactant to determine maximum possible product.
Q5: What units should I use for yield calculation?
A: While grams are commonly used, any consistent mass unit will work (mg, kg, etc.). The important factor is that both actual and theoretical values use the same unit.
