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

How many molecules are in 1 cubic centimeter of air?
The answer will depend on the temperature and pressure.
How many liters of air in one cubic meter at 6 bar pressure?
One cubic meter always has 1000 liters, no matter what is inside. On the other hand, 6 bars is approximately 6 times the normal atmospheric pressure, so - according to the ideal gas law - the cubic meter of compressed air would be equivalent to 6 cubic meters of "normal" air.
When does a cubic meter of air have less mass?
When it is at a lower pressure or a higher temperature.
How do you convert cubic meter gas to kg?
You multiply the volume of the gas by its density. The volume will depend on the specific gas, and on the pressure and temperature of the gas. As an example, a cubic meter of air has a mass of approximately 1.2 kg/m3. For other gases, the numbers may be quite different.
How many tons is one cubic meter?
There can be no equivalence. A tonne is a measure of mass. A cubic metre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. If you are not convinced, consider a cubic metre of air. How many tonnes? Next consider a cubic metre of lead. How many tonnes? The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
How many electrons are there in the air per cubic meter?
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.
How dense on average is interstellar matter?
Density varies - in cold, denser areas there may be as many as 10^12 molecules per cubic meter; in hotter less dense areas, about only 100 ions in the same volume. One source puts the average at one million atoms per cubic meter. Compare to about 10^25 molecules per cubic meter for air.
What is the waight of a cubic meter?
Depends on what the cubic meter is made of. A cubic meter of air will be something entirely different from a cubic of water.
How many air molecules in a cubic centimeter?
10^19
How much normal meter cube of air is 1000 meter cube of air?
The grammar here is confusing. I'll take this as "Compare One cubic meter of air and 1000 cubic meter of air?" 1000 cubic meters is 1000 times more volume than 1 cubic meter
How many moles of nitrogen and oxygen are in a cubic foot?
Molecules or moles? And in a cubic foot of what? Air?
How much heat is contained in 1 cubic meter of air?
That depends on the mass, pressure, and temperature of the air in the cubic meter.
How many molecules are in 1 cubic centimeter of air?
The answer will depend on the temperature and pressure.
How many LPG liters to 1 cubic meter?
1000 litres = 1 cubic metre: of LPG or air or concrete.
How many liters of air in one cubic meter at 6 bar pressure?
One cubic meter always has 1000 liters, no matter what is inside. On the other hand, 6 bars is approximately 6 times the normal atmospheric pressure, so - according to the ideal gas law - the cubic meter of compressed air would be equivalent to 6 cubic meters of "normal" air.
What is the Molecular Density of Air?
from wikipedia http://en.wikipedia.org/wiki/HumidityHumid air is less dense than dry air because a molecule of water (m = 18) is less dense than a molecule of nitrogen(m = 28) and a molecule of oxygen (m = 32). About 78% of the molecules in dry air are nitrogen (N2). Another 21% of the molecules in dry air are oxygen (O2). The final 1% of dry air is a mixture of other gases. For any gas, at a given temperature and pressure, the number of molecules present is constant for a particular volume - see ideal gas law. So when water molecules (vapor) are introduced to the dry air, the number of air molecules must reduce by the same number in a given volume, without the pressure or temperature increasing. Hence the mass per unit volume of the gas (its density) decreases. Isaac Newton discovered this phenomenon and wrote about it in his book Opticks.
Why is the term a cubic meter of air unsatisfactory?
Because it doesn't say neither the temperature, the pressure or the humidity of the air. You need to know both the temperature, the pressure and the humidity of the air to say anything about the mass of one cubic meter of air.
