avogadro numbers of atoms
1 mole C4H10 (4 moles C/1 mole C4H10)(6.022 X 1023/1 mole C)
= 2.4 X 1024 atoms of carbon
=====================
It is hard to pinpoint how many carbon atoms are in 2.5g of butane. Roughly, the answer is 1.04 x 10^23 moles. This had to be indicated by figuring out the moles per grams first.
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.
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, 25 mole of CO2 has 25 moles of carbon atoms and 50 moles of oxygen atoms.
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
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 ------------------------------
There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 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===================
The Law of Definite Proportions states that for every mole of ethane, there will be two moles of carbon. Then there is 1 mole of carbon in one half a mole of ethane.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
