Challenge Problems
Push your limits with advanced challenges
If you have a 1 liter water sample with 2 milligrams of analyte and extract it with 50 ml of solvent, calculate the theoretical concentration of the analyte in the solvent assuming complete recovery.
💡 Hint: Remember to convert liters to milliliters.
You performed an extraction and obtained 5 mg of analyte in 25 ml. If you started with 1 mg/L in 1000 ml, calculate recovery percentage.
💡 Hint: Find the total amount that should have been present before extraction.
