Abrine solution of salt flows at a constant rate of 7 l/min into a large tank that initially held 100 l of brine solution in which was dissolved 0.1 kg 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 0.02 kg/l, determine the mass of salt in the tank after t min. when will the concentration of salt in the tank reach 0.01 kg/l? determine the mass of salt in the tank after t min.

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
