In the volume formula V = M / D, what does D represent?

In the volume formula V = M / D, what does D represent?

• A. Mass
• B. Time
• C. Density
• D. Volume

Answer: (C)

Density is the link between how much matter there is and how much space it occupies. It is mass per unit volume, D = M / V. If you solve that for volume, you get V = M / D. So in the formula V = M / D, the D represents density because you’re dividing the mass by the material’s density to obtain volume. For example, 200 g with a density of 1.0 g/cm^3 gives 200 cm^3. Time isn’t involved in this relationship, and mass or volume wouldn’t explain why you divide by density.
