A tank contains 45 liters of a chemical solution prepared by dissolving 80 g of a soluble substance in fresh water. Fluid containing 3 g of this substance per liter runs in at the rate of 4 liters/min and the well-stirred mixture runs out at 4.5 liters/min. Find the amount of substance in the tank after 20 minutes.
