When air (21 mol% O2, 79 mol% N2) is placed in contact with 1000 cm3 of liquid water at body temperature, 37°C, and 1 atm absolute, approximately 14.1 standard cubic centimeters [cm3(STP)] of gas are absorbed in the water at equilibrium. Subsequent analysis of the liquid reveals that 33.4 mol% of the dissolved gas is oxygen and the balance is oxygen

a) Estimate the Henry’s law coefficients (atm/mole fraction) of oxygen and nitrogen at 37°C

b) An adult absorbs approximately 0.4g O2/min in the blood flowing through the lungs. Assuming that blood behaves like water and that it enters the lungs free of oxygen, estimate the flow rate of blood into the lungs in L/min. (answer: 59 L blood/min)

An air bubble of 21 cm3 volume is at the bottom of a lake 32 m deep where the temperature is 4.0°C. The bubble rises to the surface, which is at a temperature of 24°C. Take the temperature of the bubble's air to be the same as that of the surrounding water. Just as the bubble reaches the surface, what is its volume?
