To determine the weight of 20 mL of water, follow these steps: 1. Use a scale: Zero it out with an empty container. 2. Add 20 mL of water to the container using a precise measuring tool. 3. Weigh the container again: Subtract the container's weight from the total. Given water's density is 1 g/mL, the weight should be approximately 20 grams. This method ensures accuracy and simplicity.
FAQs & Answers
- What is the density of water? The density of water is approximately 1 g/mL, meaning 1 mL of water weighs about 1 gram.
- How do you measure liquid accurately? To measure liquid accurately, use a calibrated measuring tool and ensure it is placed on a flat, stable surface.
- Why is it important to zero the scale? Zeroing the scale ensures that only the weight of the water is measured, not the container's weight.
- Can the weight of water change? The weight of water does not change with its volume at a constant temperature, as long as density remains the same.
