Achemist has two solutions of hno 3. one has a 40% concentration and the other has a 25% concentration. how many liters of each solution must be mixed to obtain 120 liters of a 30% solution?

40 Liter of 40% solution and 80 Liter of 25% solution should be mixed to obtain 120 liters of a 30% solution

Explanation:

Let the volume of the 40%  and 25% solution be x and y.

x + y = 120....(1)

Percentage of the will equal to the sum percentage of in x anf y volumes.

8x + 5y = 720....(2)

Solving equation (1) and (2) we get:

x = 40 L , y = 80 L

40 L of 40% solution and 80 L of 25% solution should be mixed to obtain 120 liters of a 30% solution
