What is the minimum number of nanocontainers that a person would need in their bloodstream to provide 1 hour's worth of oxygen?

I did some research and found that the average human requires 550 L of oxygen per day which means that :

(550 L O2 / day) x (1 day / 24 hours) = 22.9166667 L O2 / hour or 22916.67 mL O2 / hour

1 mL = 1 cm^3

22916.67 mL O2 / hour = 22916.67 cm^3 O2 / hour

Now convert that volume from cm^3 to nm^3

22916.67 cm^3 O2 / hour = 2.29167x10^25 nm^3 O2 / hour

So for 1 hour’s worth of O2, we need a volume of 2.29167x10^25 nm^3

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
