How many milliliters are equal to 1000 milligrams?

• A. 0.001 mL
• B. 1 mL
• C. 10 mL
• D. 100 mL

Answer: (B)

Converting mass to volume relies on density to link how heavy something is to how much space it takes up. For a liquid with density close to water, 1 milliliter weighs about 1 gram. Convert 1000 milligrams to grams: 1000 mg = 1 g. Then the volume that mass occupies is 1 g divided by the density 1 g/mL, which equals 1 mL. So 1000 mg corresponds to roughly 1 mL under that common assumption. The other volumes would correspond to different masses under the same density: 0.001 mL would weigh about 1 mg, 10 mL would weigh about 10 g, and 100 mL would weigh about 100 g. In practice, this problem uses the typical water-like density to make the 1 mL result correct.
