Since there is one carbon atom per mole in carbon tetrafluoride, the answer is 3.27 times Avogadro's Number or about 1.97 X 1024 atoms.
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
2,2 moles of plutonium: 13,248711938.1023 atoms.

4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
A mole of a substance has 6.022 E23 things of that substance. So 3 moles of Carbon-12 has 1.806 E 24 atoms.
There are 9.33 moles of carbon in 5.62 atoms of carbon.
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
1.50 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 1023/1 mole C)= 8.13 X 1024 carbon atoms===================
44 moles of 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.
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.
