What is the active ingredient content in a 20-pound bag of 25W formulation?

1. 2.5 lbs

2. 5 lbs

3. 10 lbs

4. 15 lbs

The correct answer is: 5 lbs

To determine the active ingredient content in a 20-pound bag of a 25W formulation, it is essential to understand what the "25W" designation signifies. The "25" refers to the percentage of active ingredient in the formulation, which means that 25% of the total weight is constituted by that active ingredient. In a 20-pound bag, calculating the amount of active ingredient involves finding 25% of 20 pounds. This can be done with the following calculation: 25% of 20 pounds = 0.25 x 20 = 5 pounds. Thus, the active ingredient content in a 20-pound bag of a 25W formulation is indeed 5 pounds. This is why the choice indicating 5 lbs is the correct answer. Understanding this calculation can assist in similar questions regarding formulations, as it’s a common way to represent concentrations in the context of regulatory practices and compliance with agricultural and chemical product directives.
