To calculate the mass of water in kg, use the formula: mass = volume × density. Given that the density of water is approximately 1 kg/L, if you have a volume in liters (L), the mass in kilograms (kg) will be equal to that volume. For instance, 2 L of water weighs 2 kg. This relationship holds true because water has a density of 1 kg per liter at standard temperature and pressure.

FAQs & Answers

  1. What is the density of water? The density of water is approximately 1 kg/L at standard temperature and pressure.
  2. How do you convert liters to kilograms? To convert liters to kilograms, simply multiply the volume in liters by the density of water, which is 1 kg/L.
  3. Why is the mass of water equal to its volume? The mass of water equals its volume because the density of water is 1 kg per liter, meaning 1 liter of water weighs 1 kilogram.
  4. What are the factors affecting the density of water? Temperature and pressure are key factors that can affect the density of water, but at standard conditions, it remains approximately 1 kg/L.
