Formal set up. ( Avogadro's number appears as form of 1 here )
9.00 grams 13C (1 mole 13C/13.00 grams)(6.022 X 1023/1 mole 13C)(1 mole atoms 13C/6.022 X 1023)
= 0.692 mole of 13C atoms
====================
0.615 moles
Because the 13 is Carbon's Atomic Mass so 13.0g/moles
Moles=Mass/atomic mass
Moles=8.00/13.0= 0.615 moles
It is more simple to answer this question becouse you uhave to take the number of moles you are given and divide them with the atomic number which this time is 13.
(8.00/13)=0.692
9 g of carbon-13 is equal to 0,692 moles.

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 24 moles of Carbon (C) in 2 moles of table sugar (sucrose)
1 mole of CO2 has 1 mole of carbon atoms and 2 moles 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 ------------------------------
There are 9.33 moles of carbon in 5.62 atoms of carbon.
6,1x10-3 moles of carbon 36,7350592277.1020 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.
10.08 moles (there are six carbon atoms per molecule of C6H6, hence, six times the number of moles of carbon can be produced).
0,515 g of carbon is equal to 0,043 moles.
0,666 moles
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 answer is 7,829.10 ex.23 atoms.
There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 atoms of carbon.
There are 24 moles of Carbon (C) in 2 moles of table sugar (sucrose)
