Question 1134515: In the lab Justin has two solutions that contain alcohol and is mixing them with each other. He uses 100 mili litters less of solution A than solution B. Solution A is 13% alcohol ana Solution B is 19% alcohol. How many milliliters of Solution B does he use, if the resulting mixture has 243 milliliters of pure alcohol? Answer by ikleyn(52777) (Show Source):
Your balance equation for the pure alcohol volume is
0.19x + 0.13*(x-100) = 243 milliliters of the pure alcohol,
where x is the volume of the solution B in milliliters, which is the value under the problem's question.
As soon as you have setup the balance equation, the rest is just arithmetic.
x = = 800 milliliters. ANSWER
