A brine sоlutiоn оf sаlt flows аt а constant rate of 6 L/min into a large tank that initially held 50 L ofbrine solution in which was dissolved 0.5 kg of salt. The solution inside the tank is kept well stirred andflows out of the tank at the same rate. a) If the concentration of salt in the brine entering the tank is 0.05 kg/L, determine the mass of salt in the tankafter t min. (Let x be the mass of salt at time t. Write the ODE that x satisfies and solved it.) b) When will the concentration of salt in thetank reach 0.03 kg/L
