No, 2 mL is not the same as 2 grams for all substances. While 2 mL of water weighs approximately 2 grams, the weight of 2 mL of a different substance will vary based on its density. For instance, 2 mL of oil would weigh less than 2 grams, whereas 2 mL of mercury would weigh significantly more.
FAQs & Answers
- Why isn’t 2 mL always equal to 2 grams? Because weight depends on density, 2 mL of a substance will not always weigh 2 grams. Different substances have different densities, affecting their weight for the same volume.
- How can I convert mL to grams accurately? To convert mL to grams accurately, you need to know the density of the substance and multiply the volume (mL) by the density (g/mL).
- What substances weigh less or more than water for the same volume? Substances like oil weigh less than water per mL, while heavier substances like mercury weigh more due to higher density.
