A tank contains 50 kg of salt and 2000 L of water. A solution of a concentration 0.0125 kg of salt per ater enters a tank at the rate 6 Limin. The solution is mixed and drains from the tank at the same rate. a.) What is the concentration of our solution in the tank initially? concentration = 0.025 (kg/l) b.) Find the amount of salt in the tank after 3.5 hours. amount = 38.31479 (kg) c.) Find the concentration of salt in the solution in the tank as time approaches infinity concentration 25 (kg/L)
