How many liters will give me 1ton?

The question, as stated, cannot be answered sensibly. Different gases have different densities and these are affected by their temperature and pressure. A ton of a light gas, such as hydrogen, will occupy roughly 11125 kilolitres at standard temperature and pressure. On the other hand a heavy elemental gas such as Radon will occupy roughly 103 kilolitres - only one hundredth as much.
