How many fluid ounces must be added to a full three-gallon sprayer tank?

• A. 5.0 ounces
• B. 7.5 ounces
• C. 10.0 ounces
• D. 12.5 ounces

Answer: (B)

You determine the amount to add by multiplying the labeled rate per gallon by the total gallons in the tank. If the product label calls for 2.5 ounces of concentrate per gallon, then for three gallons you need 2.5 × 3 = 7.5 ounces. So you add 7.5 ounces to the full three-gallon tank and mix thoroughly. The other amounts would reflect different per-gallon rates and would not give the correct dilution. Always follow the label's exact per-gallon rate and the recommended mixing order (fill with water, add concentrate, then agitate).
