Percentage recovery gives us an idea of the amount of pure substance recovered after the chemical reaction. Percentage recovery can be more than 100 % or less than 100 %. Usually, in any experiment performed the weight percentage recovery will be less than 100. Percent recovery values greater than 100 show that the recovered compound is contaminated.
Amount of acetaminophen initially taken = 350 mg
Amount of acetaminophen obtained after recovery =185 mg
[tex]Weight percentage recovery =\frac{mass recovered}{mass originally taken}*100[/tex]
= [tex]\frac{185 mg}{350 mg}*100[/tex]
= 52.9%
