Dimethyl sulfoxide is the chemical name for the molecular formula C2H6OS. It is comprised of carbon (C). hydrogen (H) and oxygen (O). Based on the molecular formula we know that for every one mole of C2H6OS there are 2 moles of C atoms. Therefore, using this ratio of 1 mole C2H6O : 2 moles C the answer to the problem is 8 moles C.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
1 gram carbon (1 mole C/12.01 grams) = 0.08 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 ---------------------------------
30.0 grams carbon (1 mole C/12.01 grams) = 2.50 moles 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.
To find the number of moles of dimethyl ether in 138 g, we first need to calculate the molar mass of dimethyl ether, which is 46 g/mol. Then, we can use the formula moles = mass / molar mass to find that there are 3 moles of dimethyl ether in 138 g.

There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
Chemical structure: CH3 - O - CH3 so 2 Carbons, one in each methyl group
211g of carbon dioxide are equal to 4,794 moles.
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============

85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
0,515 g of carbon is equal to 0,043 moles.
The answer is 2,17 moles carbon.
