The problem at hand is to determine how much water should be added to 20 gallons of a 15% solution to dilute it to a concentration of 12%. Let's explore multiple methods and calculations to solve this problem.Method 1: Algebraic Calculation
We start by setting up the equation based on the principle that the amount of solute remains constant during dilution. Let 'V' be the volume of the 12% solution needed.20 x 15 12 x V
Solving for 'V':V 20 x 15 / 12 25
Therefore, to dilute 20 liters of a 15% solution to 12%, we need to add 25 - 20 5 liters of water.Method 2: Percentage Calculation
Another approach is to directly calculate the volume of water needed using percentages.20 x 15 300
300 x 12% 360 ml
Since 120 ml is the initial amount, we need to add 600 ml (0.6 L) of water.
Method 3: Algebraic Equation
We can also set up an algebraic equation to solve the problem:DS V
DS1 V1 15 V1 12 V1 x 12
DS1 DS2
V1 15 V1 x 12
X 20 x 15 / 12 5 gallons
Thus, adding 5 gallons of water to 20 gallons of a 15% solution will result in a 12% solution.Method 4: Proportional Calculation
This method involves calculating based on the concentration and volume of the initial solution.15% solution means 30 liters of solution contains 15 x 30 / 100 kg of solute, which is 4.5 kg.
Let the amount of water to be added be x liters.
4.5 / (30 x) 12 / 100
Solving this equation:
360 4.5 (30 x)
360 135 4.5x
225 4.5x
X 50 / 9 ≈ 5.56 liters
Therefore, adding approximately 5.56 gallons of water will dilute the 15% solution to 12%.
