How much of a 16 index fluid is needed to create 2 gallons of a 1.5% solution?

To determine how much of a 16 index fluid is needed to create a 1.5% solution in 2 gallons, it is important to first convert gallons to ounces since the answer choices are in ounces. One gallon equals 128 ounces, so 2 gallons is 256 ounces.

Next, calculate the total amount of solute needed for a 1.5% solution in 256 ounces. A 1.5% solution means 1.5 grams of solute per 100 milliliters, or in this context, we can convert it to ounces. First, we express 1.5% in relation to ounces:

1.5% of 256 ounces = 0.015 × 256 = 3.84 ounces.

Now, since the fluid is a 16 index fluid, this means that 16 fluid ounces of the solution contains 16 ounces of solute. To find out how many ounces of the 16 index fluid are needed to obtain 3.84 ounces of solute, we set up the proportion:

If 16 ounces of fluid contains 16 ounces of solute, then to find ‘x’ ounces of fluid that would yield 3.84 ounces of solute,
