A. Determine the mass of the salt in the tank after 1 min. (mass= kg)

B. when will the concentration of salt in the tank reach 0.02 kg/L? (in minutes, round to 2 decimal places)

A brine solution of salt flows at a constant rate of 9L/min into a large tank that initially held 100L of brine solution in which was dissolved 0.15kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at the same rate. If the concentration of salt in the brine entering the tank is 0.03kg/L, determine the mass of salt in the tank after t min. When will the concentration of salt in the tank reach 0.02 kg/L ? Determine the mass of salt in the tank after t min. mass =kg
