It depends, since you are most probably (:P) not working with ideal gases.
Anyway, you should calculate the relative molecular mass and then find out how many moles it is. That way you can say:
- How particles of each element there are.
- How much the whole thing weighs.
- How much it would weigh if you were to react it with "X".

Natural gas is mostly methane. CH4. Propane is CH3-CH2-CH3. Therefore propane would be heavier. The pressure is not stated. A mole of any gas fills 22.4 liters, under STP.

Natural gas is colourless, odourless, tasteless, shapeless and lighter than air (.6 in stead of 1.0) .72KG/M3
Unlike natural gas, propane is heavier than air (1.5 times denser) 1.8 KG/M3
The density of air at sea level is about 1.2 kg/m3
