What would be the saturation concentration (mol/l) of oxygen in river in winter when the temperature is 5°c if the henry's law constant at this temperature is 1.90x103 mol/l-atm? what would be the answer in units of mg/l? plus: to see the effect of temperature on gas solubility and to practice with a different set of units, calculate the saturation concentration (in mg/l) at 20°c using a k value of 4.01x104 atm. for 5°c, 12.7 mg/l; for 20°c, 9.25 mg/l a
