The conversion of grams to milliliters (g to mL) is not straightforward because it depends on the substance's density. However, for water at 4°C, 1 mL is equal to 1 gram, as water has a density of 1 g/mL. For other substances, you'll need to know the density to convert grams to mL or vice versa.
FAQs & Answers
- Why is 1 mL of water equal to 1 gram? At 4°C, water has a density of 1 g/mL, so 1 milliliter of water weighs exactly 1 gram. This is a unique property of water due to its density at that temperature.
- How do I convert grams to milliliters for other substances? To convert grams to milliliters for substances other than water, you need to know the substance's density, usually expressed in grams per milliliter (g/mL). The formula is volume (mL) = mass (g) ÷ density (g/mL).
- Does temperature affect the conversion between grams and milliliters? Yes, temperature affects density. For example, water’s density changes with temperature, so 1 mL does not always equal exactly 1 gram unless at 4°C.
