Q. The ultimate BOD (๐ฟ0) of a wastewater sample is estimated as 87% of COD. The COD of this wastewater is 300 mg/L. Considering first order BOD reaction rate constant k (use natural log) = 0.23 per day and temperature coefficient ฮธ = 1.047, the BOD value (in mg/L, up to one decimal place) after three days of incubation at 27oC for this wastewater will be
