a lab technician has one solution that is 60% chlorinated and another that is 40% chlorinated. how much of each solution is needed to make a 100 L solution that is 50% clorine?
---------------------
60% solution DATA:
Amount is "x" L ; amount of chlorine in them is 0.6x L
-------------------
40% solution DATA:
Amount is "100-x" L ; amount of chlorine in them is 0.4(100-x)=(40-0.4x) L
------------------
Mixture DATA:
Amount is 100 L ; amount of chlorine is 0.5(100)= 50 L
-----------------
EQUATION:
chlorine + chlorine = chlorine
0.6x + 40-0.4x = 50
0.3x=10
x=33.3 L (amount of 60% solution in the mixture)
100-33.3 L = 66.7 L (amount of 40% solution in the mixture)
-----------
