Which statement best describes mass in relation to volume?

The statement that mass divided by volume equals density is correct and highlights a fundamental relationship in physics. Density is defined as the mass of an object per unit volume, which can be mathematically expressed as:

Density = Mass / Volume

This relationship is crucial in understanding how different materials behave and how they can be compared with one another. For example, if you know an object’s mass and volume, you can calculate its density, which then allows you to infer whether it will float or sink in a fluid.

Mass is a measure of the amount of matter in an object, while volume is the space that object occupies. The density gives insight into how compact the mass is within that volume, which is essential in various scientific applications such as buoyancy, material science, and engineering. Consequently, understanding this relationship between mass, volume, and density is vital for grasping more complex concepts in science.
