The weight of a 250ml cup depends on the substance it is filled with. For water, 1 ml equals 1 gram, hence a 250ml cup of water weighs 250 grams. For substances other than water, the weight can vary due to different densities. For precise measurements, you'll need to consider the density of the substance in the cup.

FAQs & Answers

  1. Why does the weight of a 250ml cup vary? The weight varies because different substances have different densities, so 250ml of one substance may weigh more or less than 250ml of another.
  2. How do you convert milliliters to grams? To convert milliliters to grams, multiply the volume by the density of the substance. For water, 1ml equals 1 gram, but for other substances, density must be considered.
  3. Is 250ml of water always 250 grams? Yes, because water has a density of 1 gram per milliliter, 250ml of water weighs exactly 250 grams.
