Does 2.5 mL Equal 2.5 g? Understanding Volume vs Mass Conversion

Learn why 2.5 mL does not always equal 2.5 g and how density affects the conversion between milliliters and grams.

16 views

No, 2.5 mL does not equal 2.5 g. This is because milliliters (mL) measure volume, while grams (g) measure mass. The conversion depends on the density of the substance. For example, 2.5 mL of water is approximately 2.5 g because water has a density of 1 g/mL. However, for other substances, the weight can vary significantly.

FAQs & Answers

  1. Why does 2.5 mL not always equal 2.5 g? Because milliliters measure volume and grams measure mass, the conversion depends on the substance's density, which varies across materials.
  2. How do I convert milliliters to grams accurately? To convert milliliters to grams, multiply the volume in milliliters by the density of the substance in grams per milliliter.
  3. Is 2.5 mL of water equal to 2.5 grams? Yes, because water has a density of approximately 1 gram per milliliter, so 2.5 mL of water weighs about 2.5 grams.
