Last Answer : answer:I wouldn’t think so, unless you include a propellant. Sorta like with the aerosol can. I don’t expect mass to matter much unless you’re driving the gas gravitically. All things being equal, I’d guess that you’re looking at the same rate of flow in both cases. But then, I’m no physicist.
