Final answer:
The formula expressing the relationship between mass (m), volume (V), and density (D) of a material is D = m / V, which states that density is the mass divided by the volume of a material.
Step-by-step explanation:
The relationship between the mass (m) of a material, its volume (V), and its density (D) is expressed by the formula D = m / V. This equation states that density is the mass of a substance divided by its volume, or in other words, it represents the mass per unit volume of the material. This is a fundamental concept in the study of matter and is used in various applications of science and engineering.
Using the formula, you can calculate the density if you have the mass and volume, find the mass if you have the density and volume (m = D x V), or determine the volume if you know the mass and the density (V = m / D). Density measurement is an important aspect of material characterization and plays a crucial role in fields such as fluid dynamics, material science, and engineering.
