Not true because density depends on several factors.

False. Density is an intrinsic property of matter, and it does not depend upon how much matter there is. For instance, the density of water is 1 gram per cubic centimeter. Whether you have on drop of water or an entire swimming pool of it, the water has the same density (assuming things like the temperature are the same and the water is free of impurities).
the density of a metal like iron is much greater than the density of air, but the mass of air in a room will be much greater than the mass of a tiny scrap of iron.
what you may be thinking of is if you have equal volumes of matter, then the greater the density the greater is the mass; however, as you ask the question, the amount of matter you have depends both on the volume and the density of the matter

Density is the mass divided by volume. Mass by itself is the measure of how much "stuff" something contains.
So the answer depends. You could increase the density of something by making it smaller (have less volume) rather than more massive (containing more stuff). You could also make something denser by adding more mass to something of the same volume.
What do you think?

No, Density is how packed something is. So lets say a bowling ball shrinks to the size of a Baseball, its density has increased dramatically but its still the same mass.

The equation of mass velocity in space is related to density in th following equation;
V^2 = Pressure of space on the moving mass divided by its density.
If the volume of the mass is contricted it would cause the mass density to increase with the local space. Thus causing velocity of the mass motion to also increase.
If the Volume is constant and the mass is increased the velocity of the mass motion decreases and vice vera.
Hence density changes of a moving mass in the above equation indicates that it causes a proportional velocity change.
Since density is the ratio of two variable increase or decrease depends on what value are inherent to the two variables.
So The answer to the question is true and not true.

density = mass / volume
this shows - in general- a direct proportion between mass and density,which means as density increases mass increases.your statement does not say always or must, it says almost, so it is true.

YES because density is directly proportional to the mass and is inversely proportional to the volume. You can manipulate any of these 2 to come up with that situation.

False, matter can be compressed into a smaller volume, the mass is unaffected.

___________________________________________
Density = mass / volume
It is true that volume remaining same, as density increases, mass increases.
If density increases and volume decreases than mass may remain same may increase or decrease depending on how much the volume increases.
