Question 263967
    How many milliliters of distilled water must be added to 30 milliliters of a 46% acid solution to reduce it to a 10% acid solution?
.
Let x = milliliters of distilled water
then
.46(30) = .10(30+x)
.46(30) = 3+.10x
13.8 = 3+.10x
10.8 = .10x
108 milliliters = x (amount of distilled water to be added)
