A tank whose volume is 150 L is initially half full of a solution that contains 100 g of chemical. A solution containing 1 g/L of the same chemical flows into the tank at a rate of 5 L/min, and the well-stirred mixture flows out at a rate of 3 L/min. Determine the concentration of chemical in the tank just before the solution overflows.
