For a 1000-gallon tank requiring surfactant at a time concentration of 0.25%, how much surfactant must be added?

• A. 2 quarts
• B. 5 quarts
• C. 10 quarts
• D. 15 quarts

Answer: (C)

To determine the amount of surfactant needed for a 1000-gallon tank at a concentration of 0.25%, it’s essential to first convert the concentration percentage into a usable amount in gallons. When calculating the amount of surfactant required, start by converting the percentage to a decimal for calculation purposes. The percentage of 0.25%, when converted, is 0.0025. Next, multiply this decimal by the total volume of the tank: 0.0025 (concentration) × 1000 gallons (total volume) = 2.5 gallons of surfactant. Since the choices are given in quarts, convert gallons to quarts (there are 4 quarts in a gallon): 2.5 gallons × 4 quarts/gallon = 10 quarts. Thus, the correct amount of surfactant to add to the tank is 10 quarts, corresponding to the choice given. This calculation is essential for ensuring that the weed management solution is effective and properly dosed according to the required concentration.
