    I have a liquid mixture that is 41% chemical and 59% water. How much water do I add to each ounce of the mixture to dilute it to 25% chemical and 75% water? Thanks.

    Are these ratios mass or volume ratios? If mass what are the densities? By ounce do you mean fluid ounce?

    Volume. Fluid. Thanks. (And yes, I know I should be able to figure this, but I am having brain flatulence.)

    You have to add 0.64 oz. of water to each oz. of the mixture

    Can you figure out how I got that answer?

    .41/.25 = 1.64
    1.64 - 1 (oz. of 41% mixture) = .64 (oz. of water)

    So, for a 32 ounce bottle of 25% solution, I use ≈19.5 oz. of 41% mixture and ≈12.5 oz. of water.

    :)
