Amount obtained (how much stuff you ended up with)/ Starting amount ( how much stuff you originally started with) x 100= percent recovery

Amount obtainedx 100 = percent recovery

Starting amount

Example:

I started with 10g of some impure compound, I purified the compound and ended up with .25g, to find the percent recovery simply plug in numbers...

.25/10 x100= 2.5% recovery

What is the formula to calculare the percent recovery in assay or related substance?

The formula to calculate the percent recovery in an assay or related substance is: [ \text{Percent recovery} = \left( \frac{\text{Amount detected}}{\text{Amount spiked}} \right) \times 100% ] This formula helps to determine the efficiency of the assay in detecting the target substance by comparing the measured amount to the known amount added.


Which of the major physical laws of chemistry does the percent recovery test?

The percent recovery test is related to the law of conservation of mass. It helps determine the efficiency of a chemical reaction or separation process by comparing the actual yield to the theoretical yield, which is based on stoichiometry.


How do you calculate relative recovery?

Relative recovery is calculated by dividing the amount recovered from a process by the theoretical maximum amount that could be recovered. The formula is: (recovered amount / theoretical maximum amount) * 100. This calculation is often used in fields such as chemistry and metallurgy to evaluate the efficiency of a recovery process.
