Some wastewater treatment plants use air (oxygen partial pressure in air = 0.209 atm). Calculate the concentration of dissolved oxygen in equilibrium with Air in mg/L. The equilibria constant for oxygen is 550 atm/Molar Atomic Number H= 1, C= 6,N = 7,Cr = 24, Na = 11, CI 17,1= 53, Al = 13, S = 16,0 =8, Ca= 20, Mg= 12 K=19, Ag= 47, Ba = 56, Fe = 26, F = 9 9 (Atomic Weights (all in g/mol H= 1,C = 12, N = 14, Cr = 52, Na = 23, CI = 35.45, I= 126.9, Al = 27, S= 32, 0 =16, Ca= 40, Mg= 24, K=3 9.1, Ag = 107.86, Ba = 137.3, Fe = 55.85, F= 19 %3!
