I need to know how to calculate a mixture formula.
I have a 5-gallon premixed solution of 40%.
I need to dilute the solution to 150-gallons of 8% solution.
How much water and how much pre-mixed solution is required for the dilution and how is this calculated?
:
Let x = amt of 40% mixture is required
the resulting amt is to be 150 gal, therefore:
(150-x) = amt of water required
:
.40x = .08(150)
.40x = 12
x = 12/.4
x = 30 gal of 40% mixture, since you only have 5 gal, it's impossible to make 150 gal of an 8% mixture
