1 mL of water has a mass of 1 gram. This is because the density of water is 1 gram per milliliter (g/mL), making it a straightforward conversion. This property is unique to water under standard conditions, making it a convenient reference point for measurements.

FAQs & Answers

  1. Why does 1 mL of water weigh 1 gram? 1 mL of water weighs 1 gram due to its density being defined as 1 gram per milliliter, a unique property under standard conditions.
  2. How is the density of water measured? The density of water is measured using a balance for mass and a graduated cylinder for volume, confirming the 1:1 ratio under normal temperatures.
  3. Does the mass of 1 mL of water change with temperature? Yes, while 1 mL generally equals 1 gram, variations in temperature and pressure can slightly affect water's density.
  4. What are the uses of knowing water's mass? Knowing water's mass is essential for scientific calculations, cooking, and various applications in chemistry and physics.
