No, 1 gram is not always equivalent to 1 mL. This equivalence only holds true for substances with a density of 1 gram per milliliter, such as water at a certain temperature and pressure. For substances with densities greater or less than 1 g/mL, the volume will differ. Always consider the density to determine the relationship between mass (grams) and volume (mL) accurately.

FAQs & Answers

  1. Why is 1 gram not always equal to 1 milliliter? Because the relationship between grams and milliliters depends on the density of the substance. Only substances with a density of 1 gram per milliliter, like water under specific conditions, will have this equivalence.
  2. How do I convert grams to milliliters for different substances? To convert grams to milliliters, divide the mass in grams by the substance's density (grams per milliliter). The formula is Volume (mL) = Mass (g) / Density (g/mL).
  3. What affects the density of a substance? Density can be affected by temperature, pressure, and the specific composition of the substance, making it important to consider these factors during conversions.
