There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 atoms of carbon.
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.
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon atoms
There are 1.03 x 10^24 atoms of carbon in 4.25 moles of carbon tetrabromide (CBr4). This can be calculated by multiplying Avogadro's number (6.022 x 10^23) by the number of moles of carbon in CBr4 (4).
4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen 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 9.33 moles of carbon in 5.62 atoms of carbon.
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
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.
1.50 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 1023/1 mole C)= 8.13 X 1024 carbon 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.
0,515 g of carbon is equal to 0,043 moles.
0,666 moles
To determine the number of moles of ibuprofen containing 7.4x10^25 atoms of Carbon, we first find the number of moles present in 1 mole of ibuprofen. Ibuprofen's molecular formula is C13H18O2, so 1 mole of ibuprofen contains 13 moles of Carbon atoms. To find the moles of ibuprofen containing 7.4x10^25 Carbon atoms, we divide 7.4x10^25 by 13.
