Stoichiometric reacting masses and volumes of gases

There is a very interesting factor about gases regarding the number of moles of the gas.

That is one mole of any gas under the same temperature and pressure occupy the same volume. 

If the temperature and pressure is the room temperature and pressure the volume occupied by any gas is 24dm^{-3.  Therefore whether the gas is carbon doixide , hydrogen or even water vapour under R.T.P. (romm temperature and pressure) the volume occupied by one mole of any of these gases is 24l. In other words under r.t.p 24 l of any gas contains one mole of the gas. This information can be used for many calculations involved in gases.}

^{We can use the following equation to do perform calculations involving the gases.}

number of moles of the gas= volume occupied by the gas/ molar volume

n= v/ mv 

^{e.g: what is the volume occupied by 88g of CO2  under r.t.p?}

 ^{number of moles of carbon dioxide}

^{n= m/Mr}

n= 88/ 44

n=2

volume occupied by 2 moles of carbon dioxide

n= v/mv

2=v/24

v= 48 dm^-3
