probably not. gas fills its container regardless of volume. it's not like ammo where each shot takes the same weight.
the unit you would be looking for is probably joules per shot. not very practical since it's a scientific unit and tanks are not labeled in metric, so every time you have another tank you would have to pick your brains out.
