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 -----------------------------------------------------
To calculate the number of moles of carbon dioxide in 19 grams, divide the given mass by the molar mass of carbon dioxide, which is approximately 44 grams/mol. Therefore, 19 grams of carbon dioxide is equal to 19/44 ≈ 0.43 moles.
Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.
The balanced equation for the reaction is: CH₄ + 4Cl₂ → CCl₄ + 4HCl Using the stoichiometry of the reaction, one mole of chlorine (Cl₂) produces one mole of carbon tetrachloride (CCl₄). Since the molar mass of Cl₂ is 70.91 g/mol and that of CCl₄ is 153.82 g/mol, 709.0 grams of chlorine would produce 709.0 grams of carbon tetrachloride.
There are 4 chlorine atoms in a molecule of carbon tetrachloride. Calculate the number of moles of carbon tetrachloride in 55 ml using the density provided. Then use Avogadro's number (6.022 x 10^23) to determine the number of chlorine atoms present.

85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
To calculate the number of moles of carbon dioxide in 19 grams, divide the given mass by the molar mass of carbon dioxide, which is approximately 44 grams/mol. Therefore, 19 grams of carbon dioxide is equal to 19/44 ≈ 0.43 moles.
About one half mole. 6 grams carbon (1 mole C/12.01 grams) = 0.4996 moles of carbon --------------------------------- that is, 0.5 moles carbon ---------------------------------
0,666 moles
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
450 moles of C2H4 contain 10.815,43 g carbon.
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
30.0 grams carbon (1 mole C/12.01 grams) = 2.50 moles carbon ===============

Diamonds are all carbon. just divide 1200 grams by 12.01 grams per mole carbon.
The answer is 3,99 moles of carbon dioxide.
