Question 195320: In a chemistry class, 9 liters of a 4% silver iodide solution must be mixed with a 10% solution to get a 6% solution. How many liters of the 10% solution are needed? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let = liters of 10% solution needed
In words:
(liters of silver iodide)/(total liters of solution) = 6%
Multiply both sides by
4.5 liters of the 10% solution are needed
check:
OK
