a tank contains 50kg of salt and 1000 L of water. A solution of a concentration 0.025 kg of salt per liter enters a tank at the rate 9L/min. The solution is mixed and drains from the tank at the same rate.  what is the concentration of our solution in the tank initially concentration = ? (kg/L) find the amount of salt in the tank after 3 hours. amount = ? kg c) Find the concentration of salt in the solution in the tank as time approaches infinity. concentration = ? (kg/L)
