Problem- By titration, a water sample which was diluted tenfold had an initial DO of 9.08 mg/L, a final DO of 3.93 mg/L, an initial dilution water DO of 8.29 mg/L and a final dilution water DO of 10.32 mg/L. Calculate the BOD of this sample of water. Give your answers in mg/L to two decimal places.
Provide complete steps to solve the above question any help is appreciated
