211g of carbon dioxide are equal to 4,794 moles.
80,0 moles of CO2is equal to 3 520,8 g.
The answer is 64,9 moles.
To determine the number of moles of carbon dioxide produced when hexane is burned, we need to consider the balanced chemical equation for the combustion of hexane, which is C6H14 + 19/2 O2 -> 6 CO2 + 7 H2O. From the balanced equation, we can see that for every mole of hexane burned, 6 moles of carbon dioxide are produced. Therefore, if 84.4 moles of hexane is burned, 6 * 84.4 = 506.4 moles of carbon dioxide would be produced.
To find the number of moles of oxygen atoms in a 254 g sample of carbon dioxide (CO₂), first calculate the molar mass of CO₂, which is approximately 44 g/mol (12 g/mol for carbon and 32 g/mol for two oxygen atoms). The number of moles of CO₂ in the sample is 254 g ÷ 44 g/mol = about 5.77 moles. Since each molecule of CO₂ contains two oxygen atoms, the total number of moles of oxygen atoms is 5.77 moles × 2 = approximately 11.54 moles of O atoms.
2.1 moles Carbon dioxide (6.022 X 1023/1 mole CO2) = 1.3 X 1024 molecules of carbon dioxide =============================
211g of carbon dioxide are equal to 4,794 moles.
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
To calculate the number of moles of carbon dioxide in 19 grams, divide the given mass by the molar mass of carbon dioxide, which is approximately 44 grams/mol. Therefore, 19 grams of carbon dioxide is equal to 19/44 ≈ 0.43 moles.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.
80,0 moles of CO2is equal to 3 520,8 g.
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.
To convert from molecules to moles, divide the given number of molecules by Avogadro's number, which is 6.022 x 10^23. Therefore, for 2.22 x 10^23 molecules of carbon dioxide, divide by Avogadro's number to find 0.368 moles of carbon dioxide.
To find the number of moles, first convert the mass to grams (220 mg = 0.220 g). Then, calculate the number of moles using the formula: moles = mass / molar mass. The molar mass of CO2 is about 44 g/mol, so there are approximately 0.005 moles of CO2 in 220 mg.
3.74 moles CO2 (6.022 X 10^23/1mol CO2) = 2.25 X 10^24 molecules of carbon dioxide.
To find the number of moles of carbon dioxide, you use the formula: Moles = Mass / Molar mass. The molar mass of carbon dioxide is about 44.01 g/mol. So, for 52.06 g of carbon dioxide, you would have Moles = 52.06 g / 44.01 g/mol, which equals approximately 1.183 moles.
