This is density.
No, the density is defined as the amount of mass per unit volume.
Mass per unit volume is the object's "Density".
No, the mass per unit volume is density not intensity.
Density
Not exactly. Density is the amount of mass per unit volume. In other words, mass divided by volume.

The ratio mass/volume is called density.
The amount of mass in a given volume is called density. It is usually expressed as mass per unit volume (e.g., grams per cubic centimeter).
One is the reciprocal of the other. It is more common to use "mass per volume", but in theory you could use either. If object "A" has more mass per volume than object "B", then object "B" will have more volume per mass than object "A".
The amount of matter in a given volume is represented by the density of the substance. Density is a measure of mass per unit volume, typically expressed in units like grams per cubic centimeter. By multiplying the volume by the density of the substance, you can calculate the amount of matter present.
