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
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 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.
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.
