A tank contains 70 kg of salt and 2000L of water. Pure water enters a tank at the rate 12L/min. The solution is mixed and drains from the tank at the rate 6L/min. What is the amount of salt in the tank initially? amount = ____ kg find the amount of salt in the tank after 3.5 hr amount = ____ kg find the concentration of salt in the solution in the tank as time approach infinity (tank is big enough) concentration = ??? (kg/L)
