The amount of energy stored in a substance
B
The total volume occupied by a substance

검증된 단계별 안내1
Understand that density is a physical property of matter that relates mass and volume.
Recall the definition of density: it measures how much mass is contained in a specific volume of a substance.
Express density mathematically as \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Recognize that density does not measure energy, total volume, or number of particles directly, but rather the concentration of mass within a given space.
Conclude that the best description of density is 'the amount of mass per unit volume of a substance.'
