do it with the steps plz

a 3. (Modified version of Problem 1.11) A lake with a constant volume of 10x10 m isted by a pollution-free stream with a flow rate of 5.0%. A factory recharpes 0.5 ms of a non-conservative chemical at a concentration of 75 mg/L into the lake. The chemical degrades with a first-order rate coefficient of 0.25/d Drw a diagram of the lake and write the appropriate moss balance equation Assuming that the lake is wel mixed, calculate the steady-state concentration of the chemical in the lake. Report your answer in units of som Calculate the mass of chemical of chemical that is entering the take each day, the mass of chemical leaving the lake each day, and mass of chemical that is being lost by reaction each day. If the concentration of chemical in the factory waste jumps to 150 mol, what would be the new steady-state concentration of the chemical in the skin units b C d of ppm)
