Question 454643: Six hundred liters of 50% alcohol solution was diluted to make a 40% alcohol solution. How many liters of the 50% solution needed to be replaced by pure water in order to bring the alcohol concentration down to 40%? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 600x.50=300
.4x=300
x=300/.4=750
Since you already have 600 liters of solution, you only need to add 150 liters of pure water to reduce the concentration to 40%..
