This is a mixture problem. Be careful here, as pure acid = 100% acid and water = 0% acid. As a matter of fact any time they give you water it is automatically 0 in the % column. WE have the following table based on given information:
liquid . . . . . . . . . .% . . . . . . . . . . .L . . . . . . . . .%xL
acid . . . . . .. . . . . 100 . . . . . . . . . x . . . . . . . . .100x
water . . . . .. . . . . 0 . . . . . . . . . .. 40-x . . . .. . . . 0
mix . . . . .. . . . . . 35 . . . . . . . . . .40 . . . . . .. .. . 1400
From the third column, we get
100x = 1400
x = 14.
So we have
14 Liters of pure acid
26 liters of pure water
