Question 260632: What quantity of a 50% acid solution must be mixed with a 25% solution to produce 600ml of a 40% solution? I am completely confused on what it is asking... Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Let A be the amount of 50% solution, B the amount of 25% solution.
Here's the equation for total volume:
1.
Here's the concentration equation:
2.
From eq. 1,
Substitute into eq. 2,
2.
Then from eq. 1,
.
.
.
You need 240 ml of 50% solution and 360 ml of 25% solution.
