Question 1109160: A chemist wants to get a 50% acid solution by mixing 8 liters of 60% acid solution with 20% acid solution. How much 20% solution does the chemist need? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let = liters of 20% solution needed = liters of acid in 20% solution = liters of acid in 60% solution
-----------------------------------------------
2.667 liters of 20% solution are needed
-------------------------------------------------
check:
OK
