20.95%oxygen and 78.08% nitrogen
If 2 out of 10 parts of the air in your lungs is oxygen, then the percentage of oxygen in your lungs is 20%. Therefore, you have 600 milliliters of oxygen in your lungs (3 liters x 1000 milliliters per liter x 20%).
In a one liter sample of dry air, there are approximately 780 mL of nitrogen and 210 mL of oxygen. Nitrogen makes up about 78% of dry air while oxygen makes up about 21%.
If you have 3 liters of air in your lungs and 2 tenths of that is oxygen, how many milliliters of oxygen are in your lungs?
600 milliliters of oxygen
A 1.5 liter plastic bottle contains approximately 1.5 liters (1500 milliliters) of air when empty. When you fill the bottle with water, the volume of air contained within the bottle will vary depending on the amount of water you add.
1 liter of air is equivalent to approximately 0.0353 cubic feet of air.

1,000 milliliters is the same volume as 1 liter. It weighs very little if it's full of air, or empty. It weights about 9.8 newtons (2.2 pounds) if it's full of water. It weighs a lot more than that if it's full of gold, stones, or lead.
