Use Henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.8 of water upon warming from 25degree C to 50degree C . Assume that the water is initially saturated with nitrogen and oxygen gas at 25degree C and a total pressure of 1.0atm . Assume that the gas bubbles out at a temperature of 50degree C . The solubility of oxygen gas at 50degree C is 27.8mg/L at an oxygen pressure of 1.00atm . The solubility of nitrogen gas at 50 is 14.6mg/L at a nitrogen pressure of 1.00atm . Assume that the air above the water contains an oxygen partial pressure of 0.21atm and a nitrogen partial pressure of 0.78atm .
