It depends on a number of factors such as age, heart rate and depth of breathing. However, on average a human being exhales around 40,000 PPM of CO2.

It would depend on the person's size and how active they are. Find the CO2 rates for an hour during sleep and being awake, multiply them by whatever you need and you'll figure… out an annual estimate.. However, a rough estimate (curtesy of "The Earth Blog") assuming 12 breaths per minute (resting breath rate) is 500kg The number is easy to estimate: breaths per minute x CO2 per breath x minutes per year From Wiki - the breath rate is 12 to 25 per minute. Size of breath is 500 mL. Percent CO2 exhaled is 4% so CO2 per breath is approx 0.04g ( 2g/L x .04 x .5l). CO2 Per year= 12 x 0.04 x 525600 (minutes per year) = 252kg/yr CO2 (25 breaths) = 525 Kg/yr. So - pick a number between 252 Kg/yr and 525Kg/yr 1000 lbs/year is a good figure of merit.
Normal air contains approximately 20% O2 and 0.5% CO2. When ahuman inhales, we absorb and use some of the oxygen we breathe in.Our metabolism converts that Oxygen to Carbon Di…oxide, which weexhale, or outgas. However, the process isn't perfect: we don't useall the oxygen we inhale, nor to we exhale all the carbon dioxidein our system. So, when we exhale, the exhaled breath containseither 14% or 16% oxygen, down from the 20% the air contains. Thisis, by the way, why CPR and rescue breathing work. While yourexhalent does not contain the full 20% O2 we see in free air, itcontains enough oxygen for a person to survive on. . The actual quantity depends on the size of the person.
The human lungs weighs 2.5 pounds.
1,000,000 ml. the largest ever recorded was by kim marello in the year 0f 97' it was 123,000,0000
what is the answer A. no Oxygen B. Mostly Carbon Dioxide C. Carbon Dioxide and Oxygen D. Mostly Carbon Dioxide and Carbon Monoxide E. None of this c…hoices are correct
Yes - moisture, nitrogen, alcohol vapour and any other volatile compound that happens to be in the blood or in the air that is breathed in.
the size of a footbal. if you were to unfold all of the air sacs inside of it (300) it could cover a football field.
It depends on age, gender and activity but on average a human exhales 1 KG per day? If you are thinking of global warming, then the carbon dioxide exhaled by humans (and ani…mals) does not contribute to global warming. The carbon we exhale was taken from the world very recently, so breathing is part of the carbon cycle. Alot.
Around 2 to 3 percent of exhaled breath is CO2
The diaphragm rises. CO2 is forced out. With freeing the CO2 from Hgb and the lungs, the Hemoglobin can now pick up new oxygen molecules. The volume of the thoracic cavity… decreases.
The average Canadian produces approximately 23 tonnes of Greenhouse gasses.
It should be at least 99.5 percent CO2.
This is the releasing of carbon dioxide from an animal organism during respiration.
Ppm stands for parts per million. It is a way of showing the amount of one substance in another, like carbon dioxide in the atmosphere, especially when the percentage number i…s small. For example, in July 2011, the amount of carbon dioxide in the earth's atmosphere was 392.39 ppm (or 0.039239%).
Air- with a lot of carbon dioxide and water vapor.
The air we breath in is roughly 21% O2 and 0.04% CO2 and we breath out air that is 16% O2 and 4% CO2
