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

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !
