1 gram of weight is equal to how many milliliters of fluid?

• A. 1 mL
• B. 0.1 mL
• C. 10 mL
• D. 100 mL

Answer: (A)

The concept being tested is how mass relates to volume through density. For any substance, volume equals mass divided by density. Water has a density of about 1 g per mL, so 1 gram of water occupies roughly 1 milliliter. That’s why 1 g of fluid is typically treated as 1 mL in many clinical calculations. If the fluid isn’t water, use its density (V = m/ρ) to find the volume; for example, a fluid with 0.9 g/mL density would have 1 g occupying about 1.11 mL, while a fluid with 1.5 g/mL density would be about 0.67 mL per gram.
