They would use density to measure the volume of a substance :)

If the density of the substance is known, then you can calculate it. Density = Mass/Volume, so Mass = Density x Volume
The volume and mass of a substance are independent of the substance itself, but depend upon how much there is of the substance The density of a substance is the relation between how much volume you have of a substance and how much mass that volume has (and vice-versa). It is independent of how much there is of the substance and is thus a characteristic of the substance.
False. Density is the measure of the amount of mass an object has
No, but they are related. Density = mass / volume. Mass is often informally called the "amount of substance".It can be measured by its gravitational effects (mass in kilograms or pounds, actually any 'weight'),or by its inertia (the resistance of any physical object to a change in its state of motion or rest. It is represented numerically by an object's mass).Better statement would be:Density is a measure of how much mass is in a certain volume of a particular substance.
