Oxygen, helium, hydrogen, carbon dioxide and methane are five different gases.

The reason why nitrogen isn't inert is due to the layout of electrons around the nucleus. the electrons are found in layers/shells. For all elements except the noble gases the outer most shell is incomplete. Having a complete outer shell is the most stable any atom will get as it requires massive quantities of energy to remove them. The noble gases have full outer shells and this is why they are inert. All the other elements try to achieve this state. I will use nitrogen as an example. Nitrogen has 5 electrons in its outer most shell. The closest noble gas is Neon with 8 electrons in its outer shell. For nitrogen to achieve a full outer shell it needs 3 more electrons which it will find through bonding to other elements. Basically put nitrogen isn't inert because it will react with other elements to try and achieve a full outer shell of 8 electrons.
Natural gas is methane or CH4. There are 5 atoms in natural gas.
5 moles
At STP, 1 mole of any ideal gas occupies 22.4 liters. Therefore, 5 liters of NO2 at STP will represent 0.22 moles (5/22.4), and this is the case for any other ideal gas. So, the answer is that 5 liter of ANY ideal gas will have the same number of molecules as 5 liters of NO2.
As a general rule, the noble gases do not lose or gain valence electrons because in most reactions they are considered inert.
inert or noble
Still, inert, fixed.
inert
The next inert gas if discovered whenever its atomic number must be 118.
The element with 54 electrons is Xenon (Xe). Xenon is an Inert Gas in Period 5 of the Periodic Table. Xenon has 54 electrons in 5 shells with 8 electrons in the outer shell.

Doublecheck the O, INERT is the closest I could find. See the related link for more information.

(under "normal" room temperature and pressure conditions) simply: NO, inert gas in an oil tank can cause neither contamination nor chemical reactions to gas oil in tankers. The reason is that a) inert gas is not soluble enough to be considered as an impurity in the context of gas oil, see for example http://www.springerlink.com/content/q18t7668g24877h6/ where the solubility of Helium He in water is reported to be 0,6 MICROmol/liter/torr -- compared to 27,7 for nitrous oxide at 37 deg Celsius = 32 + 9C/5 = 98,6 Fahrenheit; and b) inert gas is chemically non responsive (i.e. inactive, inert) to chemical changes and chemical reactions of the environment, such as combustion (generating the CO2 problem, worldwide) or explosion (which you can distinguish "normally" mainly by their different speed of "what happens") But inert gas, however, is too expensive (economically = in money, and ecologically = in its production/maintenance CO2- and climate- balance anc environment costs) to be used in tankers for the prevention of accidents. And: filling up the tanker with inert gas would prevent an accident by a cigarette dropped into the tank, but it would not prevent an accident (crash, for example) where the vehicle and its tank are damaged themselves (and where the air around the accident has contact again with the tank's contents), therefore. (for the purpose of preventing a dropped-in-cigarette from causing a tanker accident, filling up the tank simply with Nitrogene N2 + carbon dioxide CO2 would do it as well: N2 is approx. 80% of the "normal" air, and this mixture can be obtained for example by burning a candle under a toppled/reversed glass; when the O2 is exhausted, the candle will go out and you have the N2+CO2 mixture) There is an "un-normal" case, too: if temperatures grow too high (i.e. environment energy grows too high), inert gases as well start having chemical activity, for example by ionisation in a linear accelerator, cyclotron accelerator, Large Hadron Collider LHC Geneva etc.etc. -- but these reactions are not relevant for an oil tank on the surface of earth at room temperature up to "normal" fire temperatures.
