let me guess....by compressing it cause the particles of gases have a lot of space between them and when we compress them they become liquid thus u can find the volumew of gas...hope that helped
You don't have to find the volume ! If gas is put into a closed container, it fills it. The volume of gas in a one liter tank is one liter.
You don't

Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.
To measure the density of a gas you find the mass and volume, then divide the volume by the mass.
One still has to know the pressure and the amount(moles) of that gas, not which gas is concerned.
The ideal gas law. Pressure * Volume = moles * Gas constant R * Temperature in Kelvin Once you have moles it is easy to find mass. PV = nRT
As the volume of a given gas sample is dependent on its temperature and pressure; to find a volume of any gas which does exist, the temperature and the pressure of the system/vessel should be given directly or could be calculated.
Use the ideal gas law. PV = nRT
Charles' law
