A gas mixture at 0C and 1 atm, flowing at 1.20 ^3/s, and containing 37 mol% NH3, 16 mol% N2, and 47 mol% H2 is to be scrubbed with water containing a negligible amount of sulfuric acid also at 0C. The exit gas should contain 1% NH3 and the exit liquid should contain 23 mol% NH3. Your supervisor wants you to design a packed absorption tower to carry out this task. Specify the (a) flow of pure water into the top of the tower kg/kg*mol
