Atank contains 50 kg 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 5 l/min. 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 = (kg/l) (b) find the amount of salt in the tank after 2.5 hours. amount = (kg) (c) find the concentration of salt in the solution in the tank as time approaches infinity. concentration = (kg/l)
