Which of the following best represents the concept of density?
A
The difference between mass and volume of a substance
B
The mass of a substance divided by its volume
C
The product of mass and volume of a substance
D
The volume of a substance divided by its mass
Verified step by step guidance1
Understand that density is a physical property that relates how much mass is contained in a given volume of a substance.
Recall the formula for density, which is the ratio of mass to volume, expressed as \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Recognize that the other options either invert this ratio or combine mass and volume incorrectly (such as taking the product or difference), which do not represent density.
Confirm that the correct conceptual definition of density is the mass of a substance divided by its volume.
Therefore, the best representation of density among the options is the one stating 'The mass of a substance divided by its volume.'
