What is the density formula?

The density formula is defined as mass divided by volume. This relationship shows how much mass is contained in a specific volume of a substance. In simpler terms, density tells us how concentrated a certain amount of mass is within a given volume. This formula is fundamental in various scientific fields, including physics, chemistry, and engineering, as it helps to understand the properties of materials and substances.

In contrast to the other options provided, mass divided by volume establishes the direct relationship that density represents. The option that suggests mass plus volume does not correspond to any scientific principle regarding density. Similarly, multiplying mass by volume or presenting volume over mass does not align with the standard definition of density in scientific contexts. Therefore, the correct understanding of the density formula as mass divided by volume is essential for accurate scientific calculations and reasoning.
