No. Check out a Periodic Table that has the "atomic weight." This will give you the different weights of each element.

The density of gases like carbon dioxide, hydrogen, oxygen, and nitrogen can be compared by looking at their molecular weights. Carbon dioxide has a molecular weight of 44 g/mol, hydrogen 2 g/mol, oxygen 32 g/mol, and nitrogen 28 g/mol. Typically, gases with higher molecular weights have higher densities, so in this case, the order from least to most dense would be: hydrogen, nitrogen, oxygen, carbon dioxide.
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.
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.
In the Earth's crust, the five most abundant elements by weight are oxygen, silicon, aluminum, iron, and calcium. In water, the most abundant elements by weight are hydrogen and oxygen. In the atmosphere, the most abundant elements by volume are nitrogen, oxygen, argon, and carbon dioxide.
Carbon dioxide diffuses most rapidly among the gases listed. This is because carbon dioxide has a lower molecular weight and smaller size compared to methane, nitrogen, oxygen, and chlorine, enabling it to diffuse more quickly through a medium.
The molecular weight of carbon dioxide is heavier than oxygen. Oxygen has a molecular weight of 32 g/mol, while carbon dioxide has a molecular weight of 44 g/mol. Therefore, carbon dioxide is heavier than oxygen.

Typically, gases with higher molecular weights have higher densities, so in this case, the order from least to most dense would be: hydrogen, nitrogen, oxygen, carbon dioxide.
Carbon dioxide is denser than oxygen because it has a larger molecular weight per molecule. Each molecule of carbon dioxide (CO2) consists of one carbon atom and two oxygen atoms, making it heavier than each molecule of oxygen (O2), which consists of only two oxygen atoms. This difference in molecular weight causes carbon dioxide to be denser than oxygen.
Yes. CO2 has a weight of 44g/mol and O2 has a weight of 32g/mol.
CO2 carbon dioxide is heavier than oxygen.
Hydrogen gas is the lightest among neon, hydrogen, and carbon dioxide. Hydrogen gas has a molecular weight of 2 g/mol, while neon has a molecular weight of 20 g/mol and carbon dioxide has a molecular weight of 44 g/mol.
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.
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.
The three main elements that contribute the most to plant wet weight are carbon, hydrogen, and oxygen. These elements make up the bulk of organic matter found in plants, such as carbohydrates, lipids, and proteins.
