Absorption #$2$: Ammonia$-$Water Absorption

If an ammonia absorber has $10\%$ ammonia in the inlet gas and no ammonia in the incoming water, what fraction of the ammonia could be absorbed with an absorption factor of $A=0\mathrm{.}85$ and $N=2?N=5?$ Graph the relationship between ammonia absorbed and number of ideal stages $($N$).$ What impact does the absorption factor have on the results?
