Expert Tip
Ensure units are correctly formatted (e.g. Kelvin for gas temperatures and liters for volumes) to get chemically accurate outputs.
How this Calculator Works
This calculator allows you to solve Percent Yield problems dynamically. Adjust the input parameters using the sliders or selection menu below:
- Actual Yield (g) (Range: 1 to 200, Default: 80)
- Theoretical Yield (g) (Range: 1 to 200, Default: 100)
The results are computed instantly and updated in the results panel on the right.
Formula & Methodology
Where:
- Actual Yield: Parameter value.
- Theoretical Yield: Parameter value.
Step-by-Step Calculation Example
To calculate Percent Yield manually, follow these steps:
- Identify the input parameters. For example:
- Actual Yield (g) = 80
- Theoretical Yield (g) = 100
- Apply the formula:
Percent Yield (%) = (Actual Yield / Theoretical Yield) * 100
- Verify the calculated value which is updated instantly in the results panel on the right.
Frequently Asked Questions
What is percent yield? ▼
Percent yield measures reaction efficiency comparing actual experimentally isolated product mass to maximum theoretical yield.
What is the formula for percent yield? ▼
Percent Yield = (Actual Yield / Theoretical Yield) × 100%.
Can percent yield exceed 100%? ▼
An apparent yield > 100% usually indicates impurities, incomplete drying (retained solvent), or weighing errors.
