In a solution of water and alcohol, the ratio of water to alcohol is 4 to 1.
a) If there are 3 liters of alcohol, how many total liters of the solution are there? 15 liters
b) What is the percent of alcohol in this solution? 25%
Wouldn't this one be
* 100 = 20%?
---> c) If you have 35 liters of this solution, how many liters of water would you need to add to make a solution that is 5% alcohol?
Let x = amt of water required to accomplish this
.20(35) = .05(x+35)
7 = .05x + 1.75
7 - 1.75 = .05x
x = 105 liters of water required to obtain a 5% mixture from 35L of a 20% mixture
