Question 974470: six liters of a 30% solution of alcohol in water is mixed with 4 liters of a 50% solution of alcohol in water. What is the alcohol strength of the mixture? Thanks :) Answer by LinnW(1048) (Show Source):
You can put this solution on YOUR website! The amount of alcohol is 6*0.30 + 4*0.50 = 1.8 + 2 = 3.8 liters of alcohol.
The total mixture is 6 + 4 = 10 liters.
So the strength of the alcohol is 3.8/10 = 0.38 = 38%
