Answer:
a) 213.3 mg/L
b) 62.61 mg/L
c) 0.0225 mg/L
Explanation:
Theoretical oxygen demand (ThOD)is essentially the amount of oxygen required for the complete degradation of a given compound into the final oxidized products
a) Given:
Concentration of acetic acid, = 200 mg/L
Based on the reaction stoichiometry:
mass of = 60 g
mass of = 2(32) = 64 g
b) Given:
Concentration of ethanol, = 30 mg/L
Based on the reaction stoichiometry:
mass of = 46 g
mass of = 3(32) = 96 g
c) Given:
Concentration of sucrose, = 50 mg/L
Based on the reaction stoichiometry:
mass of = 342 g
mass of = 12(32) = 384 g
