Question 602299: Please help me to answer this problem:
There are 40 Liters of 50% acid solution that should be reduced to a 40% acid solution. How much of acid solution must be drained off with distilled water so that the resulting solution contains only 40% acid? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! percent ---------------- quantity
Acid Solution I 50.00% ---------------- x liters
Water 0.00% ------ 40 - x liters
Mixture 40.00% ---------------- 40
50.00%x+ 0.00%(40-x)=40.00%*40
50x+0(40 -x)=1600
50x =1600
/ 50
x = 32 liters 50.00% Acid Solution I
8 liters Water
8 liters will have to be drained off
