A brine solution of salt flows at a constant rate of 4 ?L/mininto a large tank that initially held 100 L of pure water. Thesolution inside the tank is kept well stirred and flows out of thetank at a rate of 3 ?L/min. If the concentration of salt in thebrine entering the tank is 0.6 ?kg/L, determine the mass of salt inthe tank after t min. When will the concentration of salt in thetank reach 0.1 ?kg/L?
