No, 1 ml is not always 1g. The relationship between milliliters (ml) and grams (g) is determined by the density of the substance. For water, 1 ml equals 1 gram because the density of water is 1 g/cm³. However, for substances with a density greater or less than 1 g/cm³, the weight of 1 ml varies. For example, 1 ml of mercury (which has a higher density) will weigh more than 1 gram, and 1 ml of oil (which has a lower density) will weigh less.
FAQs & Answers
- Why is 1 ml not always equal to 1 gram? Because the weight of 1 ml depends on the density of the substance; only water with a density of 1 g/cm³ has 1 ml equal to 1 gram.
- How do you convert milliliters to grams for different substances? To convert ml to grams, multiply the volume in ml by the density of the substance in grams per milliliter.
- What substances have a higher density than water? Substances like mercury have a higher density than water, so 1 ml of mercury weighs more than 1 gram.
- Can oil be measured as 1 ml equals 1 gram? No, oil has a lower density than water, so 1 ml of oil weighs less than 1 gram.
