14.13 The Bunsen absorption coefficients of oxygen and nitrogen in water are 0.0283 and 0.0143 respectively, at 25 C. Suppose that air is 20% oxygen and 80% nitrogen. How many cubic centimetres of gas, measured at STP, will be dissolved by 100 cm3 of water in equilibrium with air at 1 atm pressure? How many will be dissolved if the pressure is l0 atm? What is the mole ratio, N/O2, of the dissolved gas?
