Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 Λc to 50 Λc. assume that the water is initially saturated with nitrogen and oxygen gas at 25 Λc and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 Λc. the solubility of oxygen gas at 50 Λc is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 Λc is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
