No, 2 mL is not the same as 5 mg. mL (milliliters) measures volume, while mg (milligrams) measures mass. The conversion between them depends on the substance’s density. For example, 1 mL of water equals 1,000 mg due to its density of 1 g/mL. To convert mL to mg for other substances, you need to multiply by the density of the specific substance.

FAQs & Answers

  1. What is the difference between mL and mg? mL (milliliters) measures volume, while mg (milligrams) measures mass. They are not directly convertible without knowing the density of the substance.
  2. How do you convert mL to mg? To convert mL to mg, multiply the volume in mL by the density of the specific substance in mg/mL.
  3. Is 2 mL more or less than 5 mg? It depends on the substance's density. For water, 2 mL equals 2,000 mg, which is much more than 5 mg.
  4. What is the density of water? The density of water is approximately 1 g/mL, which means 1 mL of water weighs about 1,000 mg.
