Hydrogen sulfide $(H_2(S))$ is removed from the air flow of a plant at a rate of $1,239$ mol$/$s in a gas scrubber by washing with water. Gas flow contains $25$

mol$-\%$ hydrogen sulfide and $98\%$ of it must be removed. Washing water is consumed so much that the hydrogen sulfide content of the exiting fluid

flow is $8\mathrm{.}0$mol$-\%.$

Calculate the flow rate of outgoing gas and the concentration of hydrogen sulfide, as well as the amount of incoming and outgoing washing water

when clean water is used for washing.
