Use Henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.4 L of water upon warming from 25*C to 50*C . Assume that the water is initially saturated with nitrogen and oxygen gas at 25*C and a total pressure of 1.0 atm . Assume that the gas bubbles out at a temperature of 50*C . The solubility of oxygen gas at 50*C is 27.8 mg/L at an oxygen pressure of 1.00 atm. The solubility of nitrogen gas at 50*C 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.Express your answer using two significant figures.
