85.636 grams carbon (1 mole C/12.01 grams)
= 7.1304 moles of carbon
---------------------------------
0,666 moles
moles = weight in grams / molecular weight = 56 / 28 = 2 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.
The answer is 3,99 moles of carbon dioxide.
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 ===============
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.
Diamonds are all carbon. just divide 1200 grams by 12.01 grams per mole carbon.
The answer is 3,99 moles of carbon dioxide.
To determine the grams of carbon in 3.50 moles, you need to multiply the number of moles by the molar mass of carbon. The molar mass of carbon is approximately 12.01 g/mol. Therefore, 3.50 moles of carbon would be 3.50 moles * 12.01 g/mol = 42.03 grams of carbon.
Graphite is a form of carbon, so the question is basically asking how many moles of carbon are in 18.0 grams of carbon. One gram of carbon contains 12.01 moles. This can be found on a periodic table. 18.0 grams of carbon must therefore have 18 times 12.01, or 216.18, moles of carbon.
