C
Density can be measured directly, while mass has to be calculated

The correct answer is:
**B. Mass changes based on the amount present, but density doesn’t.**
Density is defined as mass per unit volume (density = mass/volume). Therefore, it is an inherent property of a substance that does not change regardless of the amount present. This makes density a more reliable identifier for a mystery substance, as it allows for comparison based on a fundamental characteristic rather than an amount that can vary.
