Calculation
_____ milliliters of polysorbate 80 (SG = 1.08) are needed to prepare a prescription that includes 48 grams of the surfactant/emulsifier (polysorbate)? Round to the nearest hundredth. Do not include units.
milliliters
Explanation & Rationale
Step 1 is to identify the weight and specific gravity (SG) Weight: 48 g Specific Gravity: 1.08 Step 2 is to calculate the volume using the specific gravity formula Volume = Weight ÷ Specific Gravity (48 ÷ 1.08) = 44.4444... Result at this step = 44.4444 Step 3 is to round to the nearest hundredth 44.4444 ≈ 44.44
