If you use 16 ounces of 30 index fluid, how many gallons of a 2.5% solution will you have?

To determine how many gallons of a 2.5% solution you can create with 16 ounces of 30 index fluid, we first need to understand the conversion between ounces and gallons, as well as the relationships between the concentrations.

Since there are 128 ounces in one gallon, 16 ounces is equal to 16/128 gallons, which simplifies to 1/8 gallon.

Next, the 30 index fluid is being mixed to form a 2.5% solution. This means that for every 100 parts of the final solution, 2.5 parts should come from the 30 index fluid.

To find out how much total solution can be made with the 16 ounces of 30 index fluid, we can set up a proportion assuming 'x' is the unknown total volume of the 2.5% solution. It can be expressed as:

0.3 (the concentration of the index fluid) x = 16 ounces

When we convert ounces to gallons, we ensure that the final answer is in gallons. After conducting the math to find the total solution in terms of the desired concentration (2.5%), we find that utilizing 16 ounces of 30 index fluid results in a total of
