A brine solution of salt flows at a constant rate of 6 L/min into a large tank that initially held 100 L of pure water. The solution inside the tank is kept well stirred and flows out of the tank at a rate of 5 L/min. If the concentration of salt in the brine entering the tank is 0.5 kg/L, determine the mass of salt in the tank after t min. When will the concentration of salt in the tank reach 0.2 kg/L? Determine the mass of salt in the tank after t min. mass= kg When will the concentration of salt in the tank reach 0.2 kg/L? The concentration of salt in the tank reach 0.2 kg/L after minutes. (Round to two decimal places as needed.)
