Question 4: A tank contains 8 L. (liters) of water in which is dissolved 32 g (grams) of chemical. A solution containing 2 g/L of the chemical flows into the tank at a rate of 4 L/min, and the well-stirred mixture flows out at a rate of 2 L/min. i. With an aid of a diagram, construct a mathematical model for this process of chemical y(t) at time t in the tank. ii. Find the amount of chemical at time t.
