Question 1165108: A laboratory technician needs to make a 20 L batch of a 40% acid solution. how can a laboratory technician combine a batch of an acid solution that is pure acid with another that is 20% to get the desired concentration. Answer by josgarithmetic(39629) (Show Source):
You can put this solution on YOUR website! More generalized, M liter quantity of T % material to be made from L % material and H % material.
You have variables assigned as
M = 20 liters
T = 40 %
L = 20 %
H = 100%
and you can assign
v, how much of the pure, 100% material to use.

Now substitute your given values and evaluate v. Use this to evaluate M-v.
