1 mL of liquid typically weighs 1 gram. This is based on the density of water, which is a handy rule of thumb for everyday calculations. However, note that the weight can vary slightly with different types of liquids.

FAQs & Answers

  1. Why does 1 mL of water weigh 1 gram? Because water has a density of approximately 1 gram per milliliter at standard temperature and pressure, making 1 mL equal to 1 gram in weight.
  2. Do all liquids weigh the same as water for 1 mL volume? No, the weight of 1 mL varies depending on the liquid’s density. For example, oils are generally less dense than water, so 1 mL of oil weighs less than 1 gram.
  3. How can I calculate the weight of different liquids? To calculate weight, multiply the volume (in mL) by the liquid’s density (grams per mL). This gives you the weight in grams.
