1 mole of Carbon is 12.01 grams. Taken from the Periodic Table, this helps us perform calculations using dimensional analysis.
1 mole = 6.02x10power 23
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...
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.
avogadro numbers of atoms
125 g of Zinc Carbonate is 1 mole and when it decomposes it forms 1 mole of Carbon Dioxide ZnCO3 = ZnO + CO2 1 mole of carbon dioxide has a mass of 44g 44g is the answer
About one half mole. 6 grams carbon (1 mole C/12.01 grams) = 0.4996 moles of carbon --------------------------------- that is, 0.5 moles carbon ---------------------------------
1 mole of carbon weighs 12,0107(8) g.
Balanced equation. C + 2Cl2 -> CCl4 10 grams carbon (1 mole C/12.01 grams)(1 mole CCl4/1 mole C)(153.81 grams/1 mole CCl4) 128 grams carbon tetrachloride produced -----------------------------------------------------
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...
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.
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon 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.

125 g of Zinc Carbonate is 1 mole and when it decomposes it forms 1 mole of Carbon Dioxide ZnCO3 = ZnO + CO2 1 mole of carbon dioxide has a mass of 44g 44g is the answer
3.5 moles CaCO3 (1 mole carbon/1 mole CaCO3) = 3.5 moles
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
About one half mole. 6 grams carbon (1 mole C/12.01 grams) = 0.4996 moles of carbon --------------------------------- that is, 0.5 moles carbon ---------------------------------
25.0 g C10H8N2O2S2 ( 1 mole C10H8N2O2S2/252.324 g)(10 mole C/1 mole C10H8N2O2S2)(6.022 X 1023/1 mole C) = 5.97 X 1023 atoms of carbon ---------------------------------------
