Challenge Problems
Push your limits with advanced challenges
A researcher measures suspended solids in a water sample and finds the concentration to be 2 mg/L. How much mass of suspended solids would be in a 10 L sample?
💡 Hint: Use the concentration formula to calculate mass.
If an instrument has a detection limit of 0.01 mg, how would one adjust sample volume to reliably detect a substance expected at 0.005 mg/L?
💡 Hint: Recall the relationship between sample volume and detection limit.
