What Is the Percent Yield Calculator?
Percent yield compares the actual amount of product obtained to the theoretically predicted maximum.
How Does the Percent Yield Calculator Work?
Divide actual yield by theoretical yield and multiply by 100.
Percent Yield Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
Percent yield above 100% indicates measurement error or impurities in the product.
How to Use the Percent Yield Calculator
- Enter actual yield (what you got) and theoretical yield (what stoichiometry predicts).
Step-by-Step Example Calculation
Actual 4.5 g, theoretical 6.0 g
Input Values:
actualYield:4.5
theoreticalYield:6
Worked Steps: Percent yield = (4.5/6.0) × 100 = 75%.
Understanding Your Result
100% = perfect reaction. Losses from side reactions, incomplete reaction, or transfer reduce the yield.
Factors That Affect the Result
- Temperature, pressure, impurities, incomplete reaction, product loss during purification.
When Should You Use This Calculator?
- Lab reports, industrial process optimization, pharmaceutical manufacturing.
Assumptions & Limitations
- Yields > 100% indicate either measurement error or impure product.
