A brine solution of salt flows at a constant rate of 6 L/min into a large tank that initially held 100 L of pure water. The solution inside the tank is kept well stirred and flows out of the tank at a rate of 5 L/min. If the concentration of salt in the brine entering the tank is 0.5 kg/L, determine the mass of salt in the tank after t min. When will the concentration of salt in the tank reach 0.3 kg/L? Determine the mass of salt in the tank after t min. mass= kg

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
