100ml of liquid doesn’t always weigh 100g. The weight depends on the liquid's density. For water, the density is 1g/ml, so 100ml of water does weigh 100g. However, for liquids like oil, which are less dense, 100ml will weigh less. Conversely, denser liquids, such as honey, will be heavier. To find the weight, multiply the volume by the liquid's density. Always check the specific density of the liquid in question for accurate measurement.
FAQs & Answers
- Does 100ml of all liquids weigh 100g? No, the weight of 100ml of a liquid varies based on its density. For example, 100ml of water weighs 100g, but lighter liquids like oil weigh less, while denser liquids like honey weigh more.
- How do you calculate the weight of a liquid? To calculate the weight of a liquid, multiply its volume by its density. The formula is: Weight (g) = Volume (ml) x Density (g/ml). Always know the specific density of the liquid to get an accurate weight.
- What determines the density of a liquid? The density of a liquid is determined by its mass and volume. Different substances have different molecular structures, which affect how closely packed the molecules are, impacting the overall density.
- Is the density of water always 1g/ml? At 4°C, the density of pure water is approximately 1g/ml. However, temperature and impurities can cause variations in the density of water.
