Mars has a gravitational pull of around 1/3rd that of Earth and a surface area of around 1/3rd that of Earth. That means that if you introduced the same ammount of atmosphere that there is on Earth, you would have the same pressure at "sea level" on Mars that you would have at sea level on Earth.
The distance from the surface to the end of the atmosphere would be 3 times that of Earth however.
The gas wouldn't just drift into outer space.

What bases do you have to believe that the gas will not drift off into outer space? Mars simply can not hold an atmosphere that would have to extend three times farther then earth's atmosphere.
