Around 16% of oxygen in the air is needed to support fire. This level is known as the minimum oxygen concentration required for combustion.
A minimum of 16% oxygen concentration is needed to sustain a fire. This level is known as the lower flammability limit (LFL) for oxygen. Below this threshold, there is not enough oxygen to support combustion and ignite a fire.
On average, humans breathe in about 21% oxygen from the air.
Air typically contains about 21% oxygen by volume.
Oxygen makes up about 21% of Earth's atmosphere by volume.
The human body is composed of approximately 65% oxygen by mass. Oxygen is essential for many bodily functions, including cellular respiration and energy production.

Oxygen is colourless, support burning but don't smell.
There is no answer , -that is an impossible question.
On average, humans breathe in about 21% oxygen from the air.
Air typically contains about 21% oxygen by volume.
Oxygen makes up about 21% of Earth's atmosphere by volume.
To determine how many liters of oxygen represents 40 percent, you need to know the total volume of the mixture. For example, if you have 100 liters of gas, then 40 percent of that would be 40 liters of oxygen. Thus, the specific volume of oxygen depends on the total volume you’re considering.
Oxygen comprises about 47% by weight of Earth's crust
Approximately 21% of Earth's atmosphere is composed of oxygen.
The answer depends on the context: in the atmosphere, dissolved in the oceans, or whatever,
The human body is composed of approximately 65% oxygen by mass. Oxygen is essential for many bodily functions, including cellular respiration and energy production.
To extinguish a fire, you typically need to remove one or more of the elements of the fire triangle: heat, fuel, or oxygen. This can be achieved by cooling the fire (removing heat), removing combustible materials (fuel), or smothering the fire to cut off oxygen. The specific approach depends on the type of fire and its environment.
