Question 231530
If I have one gallon of product wih an active ingredient of 5% and would like to dilute the product with water to make a solution with .75% active ingredient, how many gallons of water would I need to add?
----------------
There's 0.05 gallon of active ingredient in the gallon.
Find how many gallons total would make that 0.0075 of the total.
0.05/total = 0.0075
total = 0.05/0.0075 gallons
total = 500/75 = 20/3 gallons.
Add 20/3 - 1 gallons = 17/3 gallons of water
17/3 = 5 2/3 gallons.
