No, 100 mL is not necessarily equal to 100g. The relation between milliliters (mL) and grams (g) depends on the density of the substance. For water, 100 mL is approximately equal to 100g because the density of water is 1 g/mL. However, for substances with a different density, the weight of 100 mL varies.

FAQs & Answers

  1. Why does 100 mL not always equal 100 grams? Because grams measure weight and milliliters measure volume, the conversion depends on the density of the substance, which varies.
  2. How do you convert milliliters to grams accurately? To convert milliliters to grams accurately, multiply the volume (mL) by the density (g/mL) of the substance.
  3. Is 100 mL of water really 100 grams? Yes, 100 mL of water approximately equals 100 grams since water has a density close to 1 g/mL at room temperature.
