Well this is more of a chemistry question then math questions. It depends on a few factors which you haven't listed. Gas properties under normal conditions can be found using the gas law equation: PV=mRT, where 'P' is the pressure of the gas; V is the volume of the gas; m is the mass of the gas; R is the gas constant; and T is the temp of the gas. So to answer your question, someone would need to know what pressure of the air, the temp of the air. R can be looked up on a chart in most chemistry books or thermodynamics books and V you have given to us. One you have P and T you can solve for m, in kg.
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 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 it is at a lower pressure or a higher temperature.
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.
The answer will depend on the temperature and pressure.
A kilogram is a measure of mass. A cubic metre is a measure of volume. The two measure different things and it is not sensible to even consider converting from one to the other. If you are not convinced, consider a cubic metre of air. How many kilograms? Next consider a cubic metre of lead. How many kilograms?
As the density of Oxygen at 0º C is 1.429 kg/m³ i.e. cubic meters * density = kilograms so, 1 cubic meter of oxygen would weigh 1.429 kilograms.
The conversion rate from cubic meter to kilogram will vary depending on the substance being measured. For example, 1 cubic meter of water has a mass of 1000 kilograms, while 1 cubic meter of air would have a much lower mass. To convert cubic meters to kilograms, you need to know the density of the substance.
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.
Assuming that a kilo refers to a kilogram, you don't. A kilogram is a measure of mass. A cubic metre is a measure of volume. The two measure different things and it is not sensible to even consider converting from one to the other. If you are not convinced, consider a cubic metre of air. How many kilograms? Next consider a cubic metre of lead. How many kilograms?
Depends on what the cubic meter is made of. A cubic meter of air will be something entirely different from a cubic of water.
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
You don't! A kilogram is a measure of mass. A cubic metre is a measure of volume. The two measure different things and it is not sensible to even consider converting from one to the other. If you are not convinced, consider a cubic metre of air. How many kilograms? Next consider a cubic metre of lead. How many kilograms?
Being a gas, the density of air can vary a lot, depending on its temperature and pressure. At sea level, it is usually close to 1.2 kilograms per cubic meter.
That depends on the mass, pressure, and temperature of the air in the cubic meter.
1 cubic meter = 0.35314667 brass 1 brass = 2.831684659 cubic meters
A kilogram is a measure of mass. A cubic foot is a measure of volume. The two measure different things and it is not sensible to even consider converting from one to the other. If you are not convinced, consider a cubic foot of air. How many kilograms? Next consider a cubic foot of lead. How many kilograms?
