Understanding the Difference: Specific Gravity vs. g/ml
Explore the key differences between specific gravity and g/ml in this concise Q&A video.
0 views
Specific gravity is not the same as g/ml. Specific gravity is a dimensionless unit that measures the ratio of the density of a substance to the density of water at a specific temperature. In contrast, g/ml (grams per milliliter) is a unit of density used to express how much mass is contained in a given volume of a substance.
FAQs & Answers
- What is the difference between specific gravity and density? Specific gravity is a ratio that compares a substance's density to the density of water, while density measures mass per unit volume (e.g., grams per milliliter).
- Why is specific gravity a dimensionless unit? Specific gravity is dimensionless because it is a ratio of two densities, which have the same units and thus cancel each other out, leaving a pure number.
- How do you calculate specific gravity? To calculate specific gravity, divide the density of the substance by the density of water at the same temperature. The formula is: Specific Gravity = Density_substance / Density_water.
- In what applications is specific gravity used? Specific gravity is commonly used in various fields like chemistry, engineering, and geology to determine the purity of substances, or to assess concentration in solutions.
