A 32 grams of a certain substance was initially poured and dissolved in an 18-liter container full of water. Then a solution that contains 2 grams/liter of this substance was fed and allowed to flow into the container at a rate of 4 liters/min. After the solution is mixed thoroughly in the tank, an outflow was allowed at a rate of 2 liters/min. Determine the amount of the substance in the container after 20 minutes.
