Final answer:
To make 2 gallons of a 2% dilute solution from a 32 index fluid, 5.12 ounces of the 32 index fluid are needed.
Step-by-step explanation:
To determine how many ounces of a 32 index fluid are needed to make 2 gallons of dilute solution having an index of 2%, we need to understand the conversion between gallons and fluid ounces and work through the dilution calculation.
First, we convert 2 gallons to fluid ounces using the unit equivalence of 1 gallon equal to 128 fluid ounces:
- 2 gallons × 128 fluid ounces/gallon = 256 fluid ounces
Since we want a 2% solution, we need to calculate the amount of the 32 index fluid needed:
- (2% solution) × (256 fluid ounces) = 5.12 fluid ounces of 32 index fluid
Therefore, you would need 5.12 ounces of the 32 index fluid to achieve a 2% index in 2 gallons of the dilute solution.
