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.
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
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.
If you mean atoms then two, if molecules one.

85g of oxygen = 85/16 moles of O atoms = 5.3125 moles There are 2 moles of oxygen atoms per mole of carbon dioxide, so we have 2.65625 moles of carbon dioxide. This is 2.65625 x 44 g = 116.875 g.
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 25 mole of CO2 has 25 moles of carbon atoms and 50 moles of oxygen atoms.
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432

30 moles
The answer is 3,99 moles of carbon dioxide.
no. of atoms = no. of moles * avogadros no. no. of atoms = 6 * 6*1023 no. of atoms = 3.6*1024 (ans)
If you mean atoms then two, if molecules one.
211g of carbon dioxide are equal to 4,794 moles.
