Quinine - C20H24O2N2 - contain 74,074 % carbon; the molar mass is 324,42 g.
Since quinine has a nitrogen atom in its chemical formula, 1 mole of quinine contains 1 mole of nitrogen atoms. Therefore, in 2.5 x 10^-2 moles of quinine, there are also 2.5 x 10^-2 moles of nitrogen atoms.
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 ===============
Quinine is a drug with chemical formula C20H24N2O2. In each molecule of quinine there are 20 carbon atoms. Thus in 4.0 moles of quinine, there would be 80 moles of carbon.
Since quinine has a nitrogen atom in its chemical formula, 1 mole of quinine contains 1 mole of nitrogen atoms. Therefore, in 2.5 x 10^-2 moles of quinine, there are also 2.5 x 10^-2 moles of nitrogen atoms.
You can figure this question out by looking up quinine to find its chemical formula. The number of moles of hydrogen will be the number of hydrogen in the chemical formula. Once you see the chemical formula is C20H24N2O2 then you know that there are 24 moles of hydrogen for every one mole of quinine.
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
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.
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.
