Oxygen makes up about 21% or approximately 1/5 of the air.
Roughly about 21% of air is oxygen.
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.
Approximately 21% of the air we breathe is made up of oxygen.
FiO2 stands for Fraction of Inspired Oxygen, which represents the percentage of oxygen in the air that is being inhaled. It is commonly used in medical settings to monitor and adjust oxygen therapy for patients.
1. Oxygen is made from...oxygen atoms. 2. Oxygen is a diatomic molecule. 3. Natural oxygen has three isotopes (types of atoms): 16O, 17O, 18O.
Roughly about 21% of air is oxygen.
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.
Well; putting simply, 21%
Air: 78% nitrogen, 21% oxygen, 1% other. We breathe oxygen and other molecules.
Approximately 21% of the air we breathe is made up of oxygen.
we take in oxygen via the air. the air is made up of 21% oxygen and oxygen is produced by many things. our lungs intake the air. through the mouth and nose.
the earth air is made of air, oxygen, water and helium
Rocket Fuel. Ozone. Air.
nitrogene and oxygen :)
Oxygen
It is normally know as 'air' and air is made up mostly of nitrogen and oxygen. Oxygen is the gas that the body needs to survive.
Part of air is made up of oxygen without which fire can't happen. Air can feed a fire; it contains oxygen.
