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.
621.35 grams is the mass given by wiki. So, since diamonds are mostly pure carbon............. 621.35 grams C (1 mole C/12.01 grams) = 51.736 moles of carbon
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
30.0 grams carbon (1 mole C/12.01 grams) = 2.50 moles 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 ---------------------------------
0,666 moles
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
450 moles of C2H4 contain 10.815,43 g carbon.
2,55 moles of the compound CO have 71,4 grams.
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
Diamonds are all carbon. just divide 1200 grams by 12.01 grams per mole carbon.
22 grams carbon dioxide (0.5 moles)
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.
621.35 grams is the mass given by wiki. So, since diamonds are mostly pure carbon............. 621.35 grams C (1 mole C/12.01 grams) = 51.736 moles of carbon
