∙ 11y agoalot i think ;) but im not sure so you might want to put in the effort of finding out instead of asking soo,,
=))
Wiki User
∙ 13y agoOf course. It's molecular form is 02 which has a molar mass of 36.04 g/mol.
Wiki User
∙ 14y agoYes, anything that has mass has weight in a gravitational field.
The density of oxygen is 1.308 g/L

Would a Burning fuel be a chemical or physical change?
Petrol or gasoline is basically octane - C8H18 and when it burns in air (oxygen) it converts to Carbon Dioxide and water and heat. It is thus a chemical change. Each carbon atom in the fuel has approximately two hydrogen atoms attached to it, and so its reduced molecular weight is a multiple about 14. In the combustion process each carbon atom is combined with two oxygen atoms of atomic weight 16, to produce CO2 with a molecular weight of 44. In addition, the two atoms of hydrogen are united with one further oxygen atom to produce water with a molecular weight of 18. So (approximately) 14 kg of fuel reacts with 48 kg of oxygen to produce 44 kg of carbon dioxide and 18 kg of water.
What is the mass of a carbon dioxide molecule?
44.010 g/mol You can sum up atomic weight of 1 carbon and 2 oxygen to this figure.
What is the atomic number for carbon dioxide?
Carbon Monoxide is a compound with symbols of CO compounds do not have atomic numbers. Carbon is an element with the atomic number 6 oxygen is an element with the atomic number 8
How many moles of carbon are there from the original sample of 11.0 grams of carbon dioxide and 4.50 grams of water with a combustion of 7.50 grams?
Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.
Do plants emit carbon dioxide?
Plants do produce carbon dioxide, however, the amount they produce is generally a net NEGATIVE amount. Plants, like all carbon based life forms known to date produce carbon dioxide as they use energy for biological work. This is part of the normal functioning of cells that they require oxygen in order to do this work, during which they are consuming oxygen and sugars, bonding carbon with oxygen in the process creating carbon dioxide. If they did not do this, they could not grow, and could not repair damage. HOWEVER, plants also take in carbon dioxide and use it combined with light energy in photosynthesis. This process separates the carbon and oxygen molecules, and the carbon is utilized in the preparation of stored energy ("food"). The oxygen molecules are released into the atmosphere. In a healthy plant through the bulk of its life, the plant produces more oxygen and removes more carbon dioxide than it uses oxygen and produces carbon dioxide. Exact amounts will vary based on available light, plant species, water, atmospheric condition and overall health of the plant. In >general< the more green you see on the plant, the more of the plant involved in photosynthesis and the more oxygen it produces. however, this does not tell you how much oxygen it uses (and thus how much carbon dioxide it produces). but in general, plants (and other chlorophyll laden life forms) consume more carbon dioxide than they create.
Which elements are responsible for the greater part of plant wet weight?
water/ H2O or Hydrogen and oxygen, although carbon is also highly placed
Question was raised about the mass produced when a log burns The products have a greater mass than the original log that was burned Where did the extra mass come from?
A log mainly consists of carbon and hydrogen. It has a few other elements. Carbon has an atomic weight of 12. Hydrogen has an atomic weight of 1. Oxygen comes from the air. It has an atomic weight of 16. If you take one carbon atom from the log and you take 2 oxygen atoms from the air, you get carbon dioxide. Carbon dioxide will have a weight of 12 + 16 + 16 = 44. Water is two hydrogen atoms and one oxygen. Lets see 1 + 1 + 16 = 18. Now if we take a hydrocarbon with the equivalent of 12 water molecules attached to 12 carbon atoms the water molecules will cancel each other out. We only need to work with the carbon. We start with 144 as the weight of the carbon. When we add the weight of the oxygen from the air we end up with 528. That is what we get when we add oxygen from the atmosphere.
Does methane have a higher density than oxygen and carbon dioxide?
Oxygen gas (2 Oxygen atoms per molecule) has a molecular weight of 32 g per mol, Carbon dioxide (1 Carbon atom + 2 Oxygen atoms per molecule) has a molecular weight of 44 g per mol, Methane (1 Carbon atom + 4 Hydrogen atoms per molecule) has a molecular weight of 16 g per mol, which that means when under the same temperature and pressure conditions, with the same amount of particles in the space (volume), methane would be the least dense of these gases, followed by oxygen, then finally carbon dioxide the most dense.
What is 98.5 percent of bodys weight?
oxygen, carbon, hydrogen, nitrogen, phosphorous, and calcium.
Does carbon dioxide and oxygen have mass?
Yes. CO2 has a weight of 44g/mol and O2 has a weight of 32g/mol.
Why carbon is taken as standard value for atomic weight while not others like oxygen and hydrogen?

Most of your body weight composed of?
carbon hydrogen nitrogen oxygen phophorus sulfer
How much carbon dioxide is emitted by burning one pound of coal?
Burning one pound of carbon releases about 3.6 pounds of carbon dioxide (the extra weight comes from oxygen from the air).
Are most living things made up of mostly carbon dioxide?
No,Carbon Dioxide is a waste product from energy production (respiration). When dissolved in water it becomes carbonic acid (H2CO3). Humans do have a little dissolved in blood, both as a transport mechanism, and as a pH buffer.Life is made up with cells consisting of a cell membrane filled with water and various proteins. By varying estimates, humans are about 60% or more water.The most prevalent elements in the body are Oxygen, Carbon, and Hydrogen, with the greatest number of hydrogen atoms, but since they are so light, less mass due to the hydrogen...I can see how one could come up with the assumption that with carbon and oxygen being the top two chemicals in the body by weight that it would be carbon dioxide... but it is mostly hydrocarbons and hydrogen-oxygen (water) compounds.
What is the mass of a carbon dioxide molecule?
44.010 g/mol You can sum up atomic weight of 1 carbon and 2 oxygen to this figure.
What elements account for 95 percent of your body weight?
The elements oxygen, carbon, hydrogen, and nitrogen a comfortable 95% your body weight.
