Answer: ________________________________ Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! --- percent ---------------- Amount
acid 24 ---------------- 18 liters
water 0 ---------------- x liters
Mixture 15 ---------------- 18 + x liters
24 * 18 + 0 x = 15 ( 18 + x )
432 + 0 x = 270 + 15 x
0 x -15 x = -432 + 270
-15 x = -162
/ -15
x = 10.8 liters water
