Calculating theoretical BOD A fruit processing plant generates wastewater that exerts a significant amount of BOD. The composition of the contaminants in the wastewater is C 5 H 9 O 3 at a mass concentration of 200 mg L -1 . (a) Balance the equation below that describes how the contaminants would be oxidized by microorganisms: C 5 H 9 O 3 + ___ O 2 ___ CO 2 + ____ H 2 O (b) Calculate the theoretical BOD of the wastewater. Express your answer in mg of oxygen per liter. 4. CLEANING UP CONTAMINANTED GROUNDWATER (former exam question!) Phenol (C 6 H 6 O : molecular weight 94 g mole -1 ) is a common groundwater contaminant. (a) In a sample of contaminated groundwater, the phenol concentration (C P ) was reported to be 80 ppb. What is the corresponding molar concentration? (b)
