Challenge Problems
Push your limits with advanced challenges
Calculate the change in concentration of a chemical A originally at 100 mg/L when 50% of the water evaporates.
💡 Hint: Use the concentration formula after accounting for the volume change.
A waste tank originally contains 600 kg of sludge with 250 mg/kg of Chemical A. After adding 2000 liters of rainwater, calculate the final concentration of A assuming no evaporation.
💡 Hint: Use mass balance and volume changes to find results.
