Moles X Molar mass / density = 1 mol X 12.01 g/mol/ 3.52g/cm3 = 3.41 cm3 . I of course used the density of diamond because, who wants graphite?
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.
There are 6.022 X 1023 atoms of carbon in 1 mole of carbon. 1 mole of anything is 6.022 X 1023, whether it's electrons, atoms, ions, molecules, cars, shoes, etc...
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.
avogadro numbers of atoms
C13H18O2 = ibuprofen 7.4 X 1025 carbon atoms (1 mole C atoms/6.022 X 1023)(1 mole ibuprofen/13 mole carbon) = 9.5 moles ibuprofen ------------------------------
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon 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.
There are 6.022 X 1023 atoms of carbon in 1 mole of carbon. 1 mole of anything is 6.022 X 1023, whether it's electrons, atoms, ions, molecules, cars, shoes, etc...
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.
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.
One mole of carbon and one mole of sodium have exactly the same number of atoms. That is what defines the mole, Avogadro's number, 6,022 X 1023 atoms per mole is the definition of mole.
avogadro numbers of atoms
C13H18O2 = ibuprofen 7.4 X 1025 carbon atoms (1 mole C atoms/6.022 X 1023)(1 mole ibuprofen/13 mole carbon) = 9.5 moles ibuprofen ------------------------------
1 mole of carbon (or 12 g) has 6 x 1023 atoms. So, 3 moles of carbon (or 36 g) has 18 x 1023 atoms
That is about the mole definition of Avogadro's number, so. 6.022 X 10^23 atoms of carbon
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 atoms of carbon.
