The Henry's law constant of oxygen in fresh water at room temperature is 1.3x10-3 M/atm. (a) Calculate the solubility of oxygen in water, in units of mmol/L and mg/L, at a 0.8000 atm total air pressure. The atomic weight of O is 16 g/mol and the mixing ratio of oxygen in the atmosphere is 20.8%. (b) A diluted sample of wastewater measured under above conditions shows a BOD of 5.9000 mg/L. Conclude whether this value can be trusted (enter 1 for 'yes' or o for 'no'). Answer: [02]mm = c(op) mg L-1 = Can be trusted (1 - yes, 0 - no) =
