To do this, you need to know the atomic weight of the element you're dealing with, found on any Periodic Table. The atomic weight is the mass in grams of the element in one mole - this will provide you with a conversion factor. So take the measurement in moles and multiply it by the atomic weight to convert to grams. Really what you're doing is dividing the number by 1 mole, and multiplying it by the equivalent of one mole, the atomic weight. That's the thought process behind unit analysis and how you get your "units to cancel".
In this case, the answer is about 78 grams C.
About one half mole. 6 grams carbon (1 mole C/12.01 grams) = 0.4996 moles of carbon --------------------------------- that is, 0.5 moles carbon ---------------------------------
The number of grams in 20 moles of carbon is 240,22 g.
30.0 grams carbon (1 mole C/12.01 grams) = 2.50 moles carbon ===============
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
The mass of 4,5 moles of carbon is 54,04815 g.
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 ---------------------------------
The number of grams in 20 moles of carbon is 240,22 g.
moles = weight in grams / molecular weight = 56 / 28 = 2 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 mass of 4,5 moles of carbon is 54,04815 g.
0,666 moles
450 moles of C2H4 contain 10.815,43 g carbon.
Diamonds are all carbon. just divide 1200 grams by 12.01 grams per mole carbon.
