A 50 ml solution of acid in water contains 25% acid.
How much water would you add in order to make a 10% acid solution?
:
Let x = amt of water to be added
:
Write an amt of alcohol equation
.25(50) = .10(x+50)
12.5 = .10x + 5
12.5 - 5 = .1x
7.5 = .1x
x =
x = 75 ml of water required
:
:
See if that's true
.25(50) = .10(75+50)
12.5 = .1(125)
