How Much Oxygen Does Mars Have?
Sarah Jenkins••6 min read
There actually isn't all that much oxygen on Mars. Most of its thin atmosphere (95 percent by volume) is carbon dioxide, or CO2. The rest is made up of 2.6 percent molecular nitrogen (N2), 1.9 percent argon (Ar), 0.16 percent molecular oxygen (O2), and 0.06 percent carbon monoxide (CO).

Also question is, how much oxygen is in the air on Mars?
Oxygen and ozoneThe estimated mean volume ratio of molecular oxygen (O2) in the Martian atmosphere is 0.174%. It is one of the products of the photolysis of CO2, water vapor and ozone (O3).
Beside above, how long can you live on Mars without a spacesuit? At most, an astronaut without a suit would last about 15 seconds before losing conciousness from lack of oxygen. (That's how long it would take the body to use up the oxygen left in the blood.)
Furthermore, can there be oxygen on Mars?

How strong is Mars atmosphere?
Under pressureRight now Mars has an atmospheric pressure of about six millibars – tiny compared to the one bar at sea level on Earth. “We would need something like a million ice cubes of carbon dioxide ice that are a kilometre across in order to do get to one bar,” says Jakosky.
Overall, Mars is cold—its average global temperature is around -80 degrees Fahrenheit—and has a much thinner atmosphere than Earth. Because it has about a sixth of the pressure of Earth's atmosphere, the planet doesn't retain heat very long, causing temperatures to drop quickly.
In addition, lithium, cobalt, nickel, copper, zinc, niobium, molybdenum, lanthanum, europium, tungsten, and gold have been found in trace amounts. It is quite possible that in some places these materials may be concentrated enough to be mined economically.
