cold air
It depends on the material the particles used is and the phase of it (plasma, gas, liquid or solid.)
Cold air has more molecules occupying space than warm air, therefore it has high pressure.
Cold air has higher pressure than warm air because there are more air molecules in a given volume, leading to more frequent collisions with the walls of the container, thus generating greater pressure.
It is not possible to provide an exact number without knowing more specific information such as the pressure, temperature, and composition of the air. However, on average, there are approximately 2.5 x 10^19 molecules in a cubic centimeter of air at sea level.
The answer will depend on the temperature and pressure.

That depends on the pressure and temperature of the air in the cubic meter. Any time you change the pressure or the temperature of a gas, you change the number of molecules in one cubic meter of it.

One cubic centimeter of water weighs one gram. Also note that a cubic centimeter is equal to one milliliter. __ NOTE__ All substances have different densities. The weight of a cubic centimeter depends on what one is weighing. 1 cubic centimeter of lead, for example, weighs 11.34  grams - but a litre of hydrogen (1,000 cc) weighs only 0.08988 grams.
A centimeter of what? Air? Lead? Water? If you want to weigh something, first you need to know all three dimensions of the object, since you can only weigh 3-dimensional objects. So, assuming the object is 1cm X 1cm X 1cm, you have a cubic centimeter. Now you need to know the density of the object. Obviously, a cubic centimeter of marshmallow will weigh less than a cubic centimeter of lead: A cubic centimeter of lead weighs 11.34 grams A cubic centimeter of water weighs 1 gram Silicone = 2.3 grams A cubic centimeter of a concentrated mass of neutrons (a former star) = 800,000,000 tons!!!!!
When a parachutist is falling with his parachute open, he is hitting air molecules. Imagine he is going at 1 cm/s, he is hitting 1 cubic cm of air molecules per second. If he goes at 2 cm/s, then he is hitting 2 cubic cm of air per second. This increases the air resistance. So as his speed increases, so does the amount of cubic cm of air molecules.
Each cubic meter of air on Earth contains about 10 trillion trillion molecules. This falls to around 4 trillion trillion at the top of Mount Everest. A hundred kilometers up, sometimes considered to be the border of space, there are around a million trillion molecules per cubic meter.
In the US, the occupational exposure limit for airborne asbestos is 0.2 fibers per cubic centimeter of air.
