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...
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.
avogadro numbers of atoms
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
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.
In 52.06g of carbon dioxide (CO2), you have 1 mole of CO2, which contains 2 moles of oxygen atoms. Each mole of oxygen atoms is equivalent to 6.022 x 10^23 atoms. Therefore, in 52.06g of CO2, there are 2 x 6.022 x 10^23 oxygen 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.
avogadro numbers of atoms
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon atoms
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
17 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 8.5 X 1023 atoms of carbon =====================
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
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. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
That is about the mole definition of Avogadro's number, so. 6.022 X 10^23 atoms of carbon
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 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.
