The amount of material in a substance is mass.
mass
The amount of material in a substance is its mass. Mass is a measure of the quantity of matter in an object and is typically measured in units such as grams or kilograms.
The density depends on the nature of a material.
material, quantity, amount, element, substance, constituents
Solubility is the measure of how much of a substance (the solute) can dissolve in another material (the solvent)

Concentration is the amount of a substance in a specified mass (or volume) of a material.
The concentration is the amount of a substance in the volume or mass of another material.
The amount of a material in a given space is its density. Density is defined as the mass of a substance per unit volume and is a measure of how tightly packed the atoms and molecules of a substance are in a given volume.
The density of a substance remains constant regardless of the amount of the substance. Density is an intrinsic property of a material and is determined by its mass and volume. Increasing the amount of substance will only change the mass and volume proportionally, thus keeping the density constant.
Intensive because it doesn't depend on the amount of material.
Matter occupies space and has mass. As such, the amount of matter present in a substance will determine its mass as well as its volume.
