Yes, it has an atmosphere so it has air pressure.
Mars has a low atmospheric pressure reading because there is a lighter atmosphere, which means less air, which means less weight or pressure.

The atmospheric pressure of Mars is 600 pascal or (0.087 psi) You're Welcome :D
It depends on what you mean. If you mean made up of as in the material that the surface mostly is then none that I know of. If you mean atmosphere then you have Venus, Mars, small amounts of it on Earth and probably on all the gas giants. Mercury and Pulto have thin atmospheres of nitrogen.
earths average air pressure is 1013mb where as mars average air pressure is 7mb
That's MARS.
mars has oceans of liquid water

I believe the planet with low air pressure and that is mostly made of CO2 is Mars.
it is mars. its surface pressure is 600Pa and has 95% co2

It would need around 4x1018 kg of air to raise Mars' atmosphere to earth's atmospheric pressure. The answer is formulated under general pressure-depth relation assuming ratio of atmosphere depth is very small to the planet's diameter. P = m.g/A P = pressure = 101300 Pascal at earth's sea level m = mass of air [=] kg g = Mars gravity = 3.7 m/s2 A = surface area of Mars [=] m2
Mars has an atmosphere with low air pressure which is mostly carbon dioxide.
