There are 0.022 moles of CO2 in a 1.76 g sample. Since there is a 1:2 ratio of O2 to CO2 in the compound, there are 0.044 moles of O2 present. This corresponds to 2.65 x 10^22 atoms of O2.
Use dimensional analysis to solve this problem. First calculate the molecular mass of CO2. This is found by (use a periodic table) adding 12.011g of C to (15.999g x2) grams of Oxygen. Once you do that, you find out that 44.009g are in 1 mole of CO2. Now, simply by looking at the equation of CO2, we can tell that 2 moles of oxygen atoms are in 1 mole of Co2 (look at the subscript for Oxygen). Now, your dimensional analysis should look like this: 254g CO2 x 1 mole CO2/44.009g CO2 x 2 mole Oxygen/1 mole CO2 The answer is 11.5 moles of Oxygen in 254g of CO2.
When 1 mole of C8H18 is burned, it forms 8 moles of CO2. Therefore, when 451 moles of C8H18 is burned, it will form 8 * 451 = 3608 moles of CO2.
The molar mass of CO2 is approximately 44.01 g/mol. Therefore, half a mole of CO2 would have a mass of around 22.0 g.

There are approximately 1.02 x 10^24 molecules of CCl4 in 4.25 mol. This is calculated by multiplying Avogadro's number (6.022 x 10^23) by the number of moles.
One mole of carbon dioxide molecules contains one mole of carbon atoms and two moles of oxygen atoms. Therefore, in half a mole of carbon dioxide molecules, there are half a mole of carbon atoms and one mole of oxygen atoms.
This can be calculated by using the number of Avogadro. It states that 1 mole is equal to 6.02214179*10^23 molecules. If 1 mole equals 6.02214179*10^23 molecules, then 0.0180 mole equals to: 0.0180 * 6.02214179*10^23 = 1.083985522*10^22 CO2 molecules.
1 mol = 6.02 * 10^23 molecules 0.018 mol = 6.02 * 10^28 * 0.018 molecules 1.0836 * 10^27 molecules of CO2
2.1 moles Carbon dioxide (6.022 X 1023/1 mole CO2) = 1.3 X 1024 molecules of carbon dioxide =============================

There are approximately 2.41 x 10^23 molecules of H2O in 0.4 moles. This calculation is based on Avogadro's number, which represents the number of particles in one mole of a substance.
To find the number of moles in 2.408 x 10^24 molecules of CO2, you can use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole. Therefore, 2.408 x 10^24 molecules / 6.022 x 10^23 molecules per mole = about 4 moles of CO2.
4.5166056 x 10^23 Take avagadro's number and multiply it by 0.75
2.65 mol * 64.07 g/mol = 169.79 g
There are approximately 1.45 x 10^24 molecules in 2.4 moles of CO2. This is calculated by Avogadro's number, which is 6.022 x 10^23 molecules/mol, multiplied by the number of moles.
