Yes, there is oxygen in the atmosphere of Mars, but it is present in very low concentrations, about 0.13%. This is much lower compared to Earth's atmosphere, which is around 21% oxygen.
In a 5 L volume of air, approximately 20% of it is oxygen. Therefore, 1 L of air would contain about 0.2 L (or 20%) of oxygen. Therefore, in 5 L of air, there would be approximately 1 L of oxygen present.
Yes, fossil fuels like coal, oil, and natural gas were formed from organic matter that once contained oxygen. However, as the organic matter decays and undergoes heat and pressure over millions of years, much of the oxygen is removed, leaving behind mostly carbon and hydrogen.
The weight of an oxygen cylinder can vary depending on its size and capacity. On average, a standard medical oxygen cylinder with a capacity of 6.8 cubic feet weighs around 13-20 pounds.
Hydrogen can ignite when the concentration of oxygen in the air is between 4% and 75%. Below 4%, there is not enough oxygen for ignition, and above 75%, the mixture becomes too rich to ignite.

It is 4.3 km, approx.
15% of 14000 = 14000*15/100 = 2100 So 15% off of 14000 = 14000 - 2100 = 11900
