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

  1. 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.
  2. 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).
  3. 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.
  4. 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.
