A tank contains 50 kg of salt and 2000 L of water. Pure water enters a tank at the rate 6 L/min. The solution is mixed and drains from the tank at the rate 3 L/min. (a) What is the amount of salt in the tank initially? amount = 50 (kg) (b) Find the amount of salt in the tank after 1.5 hours. 2000 amount = 50 2000 + (90-6)) (kg) (c) Find the concentration of salt in the solution the tank as time approaches infinity. (Assume your tank is large enough to hold all the solution.) concentration = (kg/L)
