Question 667075: how many liters of a 40% sulfuric acid solution should be mixed with 4 liters of a 24% sulfuric acid solution to produce 35% solution? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! -------------- percent ---------------- Amount
Sulphuric acid I 24 ---------------- 4 liters
sulphuric acid II 40 ---------------- x liters
Mixture 35 ---------------- 4 + x liters
24*4+40 x=35(4+x)
96+40x =140+35 x
40x-35 x =-96+140
5x=44
/ 5
x = 8.8 liters sulphuric acid II
