A tank contains 200 liters of fluid in which 30 grams of salt is dissolved Brine containing 1 gram of salt per liter is pumped into the tank at a rate of 4 L/min; the well-mixed solution is pumped out at 3 L/min. Find the salt concentration expressed in percent by mass in the tank after 5 minutes. The density of salt is 2.16 g/mL, and that of water is 1 g/mL.*
