What is the preparation of normal saline solution?

If a chemist mixes a 10 % saline solution with a 20 % saline solution to make 500 millimeters of a 16 % saline solution. How many millimeters of each solution?

  • Answer:

    Start by figuring out of 100 mL how much of each would be needed to get a 16% solution. You could do this by guess and check, or by making an equation to show how much percentage the solution is. Then you just need to multiply your answer by 5.
