The atmosphere consists of about 20%, Nitrogen being the main component at over 70%
Depends on the size of the cylinder, if the air is compressed or not and if it is compressed, to how much psi.
Less than 1 percent of Earth's water is ready for use by humans. Earth is approximately 71 percent water but of all this water only about 2.5 percent is fresh water with the rest being salt water and thus not fit for human consumption. Of the 2.5 percent fresh water the majority of this is frozen in the polar icecaps, present in soil moisture or deep underground where it is out of reach.
Oxygen was not found in the atmosphere of primitive Earth. It is so reactive that it became locked up in compounds at the time of Earths formation. These compounds were varied, but the bulk of them were mineral oxides, silicates, carbon dioxide and water. Free oxygen entered the atmosphere only after the development of blue-green algae, which produced oxygen from carbon dioxide.
1.33 grams of oxygen is carried by each gram of normal healthy hemoglobin.
too much weight from too many keys cause the cylinder to wear out. try attaching key to breakaway keychain to reduce weight.
the percentage of oxygen in the atmosphere today is about 20.95%. Or... if you round it you get the most common answer of 21%.
A standard oxygen cylinder contains around 6,000 liters of oxygen when full.
The percent of oxygen is 27. this increases the natural percent of 21 by 6 percent causing living organisms to have too much oxygen.
An XL50 oxygen cylinder weighs approximately 16 pounds when full.
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.

Oxygen makes up about 21% of the Earth's atmosphere.
Oxygen makes up about 65% of the human body by mass.
Typically, the air you breathe is comprised of 18 to 21 percent Oxygen.
Such cylinders are made in a variety of capacities.
The pressure in an oxygen cylinder is typically measured in pounds per square inch (psi) and can range from 2000 to 3000 psi, depending on the type and size of the cylinder. It's important to follow proper guidelines for handling and storing oxygen cylinders to ensure safety.
