A mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23. Therefore, a mole of ^12C contains 6.022 x 10^23 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.
Using eight significant figures, there are 6.0221421 X 10^23 carbon atoms present in a mole of 12c.
avogadro numbers of atoms
There are 1 mole of carbon atoms in 12g of carbon. This is because the molar mass of carbon is 12 g/mol, so 12g of carbon is equivalent to 1 mole of carbon atoms.
Each molecule of methane contains one carbon atom, as shown by the formula for methane, CH4. Therefore, the number of carbon atoms in one mole of methane is the same as Avogadro's Number, about 6.022 X 1023.
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.
6.023 x 1023
Using eight significant figures, there are 6.0221421 X 10^23 carbon atoms present in a mole of 12c.
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon atoms
21.7 g CCl4 (1 mole CCl4/153.81 g)(6.022 X 1023/1 mole CCl4) = 8.50 X 1022 atoms of carbon tetrachloride ===========================
0.5 carat carbon (0.2 grams/1 carat)(1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 5.0 X 1021 atoms of carbon ===================
1.50 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 1023/1 mole C)= 8.13 X 1024 carbon atoms===================
