A vacuum. However, a complete vacuum is impossible due to quantum effects.
No substance can have volume without mass or mass without volume. Milk ... and every other substance we can think of ... has both.
You will like to know the volume of the mass. Mass / volume will give you density. You can not know the density without mass and volume of the substance.
Density is determined by the mass of a substance divided by its volume. Therefore, both mass and volume do affect the density of a substance. If the mass increases without a corresponding increase in volume, the density will increase. Conversely, if the volume increases without a corresponding increase in mass, the density will decrease.

Density = Mass/Volume. You cannot calculate density without knowing BOTH mass and volume.
Density = Mass/Volume. Without information about the mass, you cannot calculate the density.
A plane figure has no thickness, so it has no volume. Without volume, it can't have any mass.
The density of an object is its mass divided by its volume. Without the volume, you cannot calculate its density.
Density is a measure of mass per unit volume. Without any indication of the volume occupied by the mass, it is impossible to answer the question.
You have changed the object's density by increasing its mass without changing its volume. Density is calculated by dividing mass by volume, so as mass increases while volume remains constant, the density of the object will also increase.
The mass of water at 25 degrees Celsius, without knowing the volume, cannot be determined. Mass is dependent on both volume and density, and without the volume of water given, it is not possible to calculate its mass.
Without knowing either the mass of an object or its density, it would be impossible to find the mass. There would be two variables and only one equation. Thus, one cannot find the mass of an object solely from its volume.
