How many total ounces are needed for a 3-gallon tank when preparing a 2.0% solution?

To determine the total ounces needed for a 3-gallon tank when preparing a 2.0% solution, you first need to convert gallons to ounces. One gallon is equivalent to 128 ounces, so a 3-gallon tank contains:

3 gallons × 128 ounces/gallon = 384 ounces.

Next, to calculate how many ounces of the active ingredient are necessary for a 2.0% solution, you'll use the following formula:

Total solution volume × Percentage concentration = Amount of active ingredient.

For a 2.0% solution, this becomes:

384 ounces × 0.02 = 7.68 ounces of active ingredient.

However, this calculation assumes that the percentage refers to the volume of the active ingredient in relation to the total volume of the solution. The total mixture must account for additional components such as water or any other solvents being used to create the solution.

In calculating the total amount of solution, including both the active ingredient and the diluent needed to create that 2.0% concentration, it would be appropriate to consider the concentration and total effective volume to determine the overall amount used. The discrepancy in the total number of ounces might arise from the assumptions about what constitutes the solution in practical application.
