How many grams of fat per 100 mL are in 20% IVFE?

• A. 10 g/100 mL
• B. 20 g/100 mL
• C. 25 g/100 mL
• D. 15 g/100 mL

Answer: (B)

In intravenous fat emulsions, the percentage indicates grams of fat per 100 mL of solution. Therefore, a 20% IVFE contains 20 grams of fat in every 100 mL. This is the defining meaning of a 20% fat emulsion, so the grams of fat per 100 mL is 20 g. (For comparison, a 10% emulsion would have 10 g per 100 mL, and so on.)
