avogadro numbers of atoms
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
To find the number of carbon atoms in 12 g of carbon (C), you first need to calculate the number of moles of carbon (C) in 12 g using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23) to determine the number of atoms in that many moles of carbon (C).
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.
1 mole of anything contains 6.022*1023 of that substance. So 1 mole of C contains 6.022*1023 atoms of C. There are 6.022*1023 shoes in 1 mol of shoes.
169 g C x 1 mole C/12.011 g x 6.02x10^23 atoms/mole = 8.47x10^24 atoms
One molecule has only one C atom.So 0.56mol has 0.56mol of C atoms
avogadro numbers of atoms
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
C + 2Cl2 ==> CCl4atoms of C needed = 2.00 mol Cl2 x 1 mole C/2 mole Cl2 x 6.02x10^23 atoms/mole = 6.02x10^23 atoms
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 C = 12.011g C = 6.022 x 1023 atoms C 0.020g C x (6.022 x 1023 atoms C)/12.011g C = 1.0 x 1021 atoms C
To find the number of carbon atoms in 12 g of carbon (C), you first need to calculate the number of moles of carbon (C) in 12 g using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23) to determine the number of atoms in that many moles of carbon (C).
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon atoms
1 mole C = 12.011g C 1.2g C x 1mol C/12.011g C = 0.10 mole C rounded to two significant figures
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.
