Answer:
Mass and volume are extrinsic properties.
A pail may contain water that is 1
kg in mass and 1
L in volume.
A drop of water may be 1
g in mass and 1
mL in volume.
Both are water, but they have different mass and volumes. Therefore you can't identify whether a substance is water just by measuring its mass and volume.
However, the ratio of the mass to volume (density) can be used to identify substances.
