1 mL does not always equal 1 g. The relationship between milliliters and grams depends on the substance's density. For water, 1 mL does equal 1 g because water's density is 1 g/mL. However, for other substances, the density varies, so the equivalence between mL and grams changes accordingly.
FAQs & Answers
- Why does 1 mL not always equal 1 g? Because the equivalence depends on the density of the substance; for instance, water has a density of 1 g/mL, but other substances differ.
- How is density defined? Density is defined as mass per unit volume, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).
- Can I convert grams to milliliters? Yes, to convert grams to milliliters, divide the mass by the substance's density. Different substances will have different densities.
- What is the density of common substances? Common densities include water at 1 g/mL, ethanol at 0.789 g/mL, and oil at about 0.92 g/mL, illustrating how conversions vary.
