Chemistry

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

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

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