How do you calculate the amount of an AI in a dry formulation?

By volume of product
By weight multiplied by percent of AI
By volume of AI per gallon
Directly from the label

The correct answer is: By weight multiplied by percent of AI

When calculating the amount of an AI (active ingredient) in a dry formulation, it is important to use weight rather than volume. This is because the concentration of the AI is based on weight, not volume. Option A is incorrect because using volume of the overall product will not accurately reflect the amount of the active ingredient. Option C is incorrect because it only accounts for the volume of the AI, not its weight. Option D may provide the percentage of the AI, but it does not calculate the actual amount needed. Therefore, the best and most accurate way to calculate the amount of AI in a dry formulation is by using weight multiplied by the percentage of AI.
