Best Answer

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
