No, 200 mL is not necessarily equal to 200 g. The equivalence of mL to g depends on the substance's density. For water, 1 mL equals 1 g, making 200 mL of water equal to 200 g. However, this ratio changes for substances with densities different from water.

FAQs & Answers

  1. Why isn't 200 mL always equal to 200 g? Because the conversion between milliliters and grams depends on the density of the substance. Water has a density of 1 g/mL, but other substances vary.
  2. How do you convert mL to grams for substances other than water? You multiply the volume in milliliters by the density of the substance (in g/mL) to get the weight in grams.
  3. What is the density of water that allows 1 mL to equal 1 g? Water has a density of approximately 1 gram per milliliter at standard temperature and pressure, making volume and mass numerically equal.
