Please solve and provide full procedure. An ammonia$-$air mixture frac

ammonia$)$ is to be scrubbed with water at $293$

$K.$ The final mol frac is $0\mathrm{.}00041$ ammonia.

Both the liquid and gas flow rates are $1\mathrm{.}36$

${10}^{-3}k\frac{g}{m^2}-s.$ Determine the no$.$ of equilibrium

stages needed. The equilibrium data for partial

pressures of ammonia over aqueous ammonia

solutions is are:
