The proportion by number of atoms in carbon dioxide is 1:2. The atomic weight of carbon is 12.011 and the atomic weight of oxygen is 15.9994. Therefore, the proportion by mass of carbon to oxygen in carbon dioxide is 12.011/(2 X 15.9994) = 0.37536 or 37.536 %, to the justified number of significant digits.

∙ 13y agoThere are 2 moles of O per 1 mole of carbon dioxide (CO2). Use the molecular weight to find the mass of oxygen & mass of carbon dioxide.
2 moles of O * (16 g O / 1 mole O) = 32 g O
1 mole of CO2*(44 g CO2/1 mole CO2) = 44 g CO2
So the % oxygen in carbon dioxide by mass is:
32 g / 44 g * (100%) = 72.7%

∙ 13y agoBy "Percentage by Msss" I assume you mean how much of the mass of Carbon Monoxide does Oxygen make up.
It's like this; one Carbon atom, one Oxygen atom. The atomic mass of carbon is about 12 AMUs (Atomic Mass Units) and Oxygen is about 16 AMUs. That gets up to 28 AMUs. 28 is close to a fourth of 100, so multiply 16 by four to get the approximate percentage: Oxygen makes up about 64% of Carbon Monoxide's mass.

What is the mass carbon present in 44g of carbon dioxide?
Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.
What is the percentage composition for CO?
The molecular mass of CO is 28. The carbon percentage by mass is ~43%. Hence the oxygen percentage by mass is ~57%.
What mass of carbon dioxide can be produced from 25.0g of C6H14 and excess oxygen?
The gram molecular mass of hexane is 86.18. Therefore, 25.0 g of hexane constitute 25.0/86.18 or 0.290 moles. Each mole of hexane contains six carbon atoms and therefore will produce six molecules of carbon dioxide by burning in an excess of oxygen. 6 X 0.290 = 1.74 moles of carbon dioxide. The gram molecular mass of carbon dioxide is 44.00. Therefore, the mass of carbon dioxide produced will be 1.74 X 44.00 or 76.6 grams of carbon dioxide, to the justified number of significant digits.
When methane is burned with oxygen the products are carbon dioxide and water If you produce 18 grams of water from 8 grams of methane and 32 grams of oxygen how many grams of carbon dioxide were pr?
If all of the quantities stated actually reacted, the law of the conservation of mass shows that the mass of carbon dioxide produced would be 40 - 18 or 22 grams.
What are the three most important dissolved gases in seawater?
1. Nitrogen. (It makes up 78% of the atmosphere) 2. Oxygen (21%) 3. Argon (1%) The local atmosphere may contain various amounts of water vapor by mass.
When methane burns carbon dioxide and water are formed The mass of carbon dioxide plus the mass of water equal the mass of the methane plus the mass of OXYGEN?
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
What law is described by the fact that the ratio of the mass of oxygen in carbon dioxide to the mass of oxygen in carbon monoxide?
law of multiple proportion
What is the mass carbon present in 44g of carbon dioxide?
Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.
What is the mass of carbon dioxide that will be formed when 3.0g of carbon is burned in 25.0g of oxygen?
11.0g
A certain mass of carbon reacts with 13.6g of oxygen to form carbon monoxide what amount of grams of oxygen would react with that same mass of carbon to form carbon dioxide?
27.2 g
When carbon is burned in air it reacts with oxygen to form carbon dioxide When 12.0 of carbon were burned in the presence of 49.8 of oxygen 17.8 of oxygen remained unreacted What mass of carbon?
37.8
What mass of carbon monoxide must react with oxygen to produce 0.69g of carbon dioxide?
0.44g CO
What law is shown by the fact the mass of carbon dioxide which forms as a product of a reaction between oxygen and carbon equals the combined masses of the carbon and oxygen that reacted?
This is the law om mass conservation.
What law is shown by the fact that the mass of carbon dioxide which forms as a product of a reaction between oxygen and carbon equals the combine masses of the carbon and oxygen that reacted?
This is the law om mass conservation.
