Percent Recovery Calculator

Percent Recovery Formula

The formula to calculate percent recovery is:
$$\text{PR} = \left( \frac{\text{SAP}}{\text{SBP}} \right) \times 100$$
Where:

• PR = Percent Recovery
• SAP = Substance Amount After Purification
• SBP = Substance Amount Before Purification

Example Calculation

If the substance amount before purification is 150 grams and the substance amount after purification is 120 grams, the percent recovery would be:
$$\text{PR} = \left( \frac{120}{150} \right) \times 100 = 80\%$$

Importance

Percent recovery is vital in chemistry and lab work, helping to determine the efficiency of purification processes by comparing the substance amounts before and after purification.

FAQ

What is percent recovery?
Percent recovery is a measure of how much of a substance remains after a purification process, expressed as a percentage of the original amount.
