To find the mass of water in an experiment, use a balance scale. First, measure the mass of an empty container and record it. Then, fill the container with water and measure the total mass. Subtract the mass of the empty container from the total mass to obtain the mass of the water. This method ensures accurate measurement by accounting for the container's weight.

FAQs & Answers

  1. How do I use a balance scale to find the mass of water? To find the mass of water using a balance scale, first weigh an empty container and note the mass. Then, fill the container with water and weigh it again. The mass of the water is the total mass minus the mass of the empty container.
  2. Why is it important to subtract the mass of the container? Subtracting the mass of the container is crucial because it isolates the mass of the water. This ensures that the measurement reflects only the water's weight, providing an accurate result.
  3. Can I find the mass of water without a balance scale? While a balance scale is the most accurate method, you can estimate the mass of water using measurements of volume and water's density. For example, 1 liter of water has a mass of approximately 1 kilogram.
  4. What common errors should I avoid when measuring water mass? Avoid errors such as not zeroing the balance with the empty container, spilling water, or using an unstable balance. Ensure you are on a flat, level surface for accurate readings.
