Can you please help in solving this and show steps

3. In a completely mixed reactor filled with clean water, a feed of a non-degradable compound C is introduced at an influent concentration of Cm = 180 mg/L and flow rate Om = 3 m'/h to run from time zero to 300 hours. The volume of the reactor is kept at a constant value of 120 m. What will be the effluent concentration from the reactor at the following times (assume that there is no reaction in the reactor): ( 12 pts ) i. Oh ii. 60 h i1i. 120 h iv. 250 h v. 450 h From the above information, what can you say about the relationship between the hydraulic retention time (V/Q) and effluent concentration when there is no reaction in the reactor? (6 pts )
