Little elementary question

Hi all…
I have a question, if I have a bottle of gas, let’s say 20 litres
The gas is at 20 atm
How many litres of gas at atmospheric pressure there are?
How is the formula?

The ratio of unpressurized to pressurized volumes is the number of atmospheres that the cylinder is pressurized to. So you just multiply the pressurized volume (20) by the number of atmospheres (20) to get 400 litres.

Yep I know that and also the equation of gas state (PV=nRT) I was just being lazy! Thanks anyway… :slight_smile:
