In brand abbreviations such as 50WP or 4F, the leading number usually refers to what?

• A. Percent by weight
• B. Percent by volume
• C. Density
• D. Molarity

Answer: (D)

The leading number shows how concentrated the product is, specifically the percentage of active ingredient by weight in the formulation. So a label like 50WP means the wettable powder contains 50% active ingredient by weight. A designation like 4F indicates a flowable formulation with about 4% active ingredient by weight. The letters (WP, F, etc.) describe the type of formulation, not the concentration. This convention is about potency expressed as weight percent, not moles per liter (molarity).
