Specific gravity relates to which property when choosing a dry measuring device?

• A. Brand
• B. Weight per volume of product
• C. Temperature
• D. Color

Answer: (B)

Specific gravity is a measure of density relative to water, which tells you how heavy a given volume of the product is. When you’re choosing a dry measuring device, you need to know the product’s weight per unit volume because a scoop or other volume-based measure will deliver different amounts of active ingredient depending on how dense the product is. A denser dry product weighs more per scoop than a lighter one, so the device must be chosen or calibrated to account for that density to achieve the correct dose. Brand, color, or even temperature are not the primary factors here—specific gravity focuses on density (weight per volume) in standard conditions.
