350 g sample of CO contain 12,49 moles.
1.305 mol CO
A 63,60 g sample of carbon is equal to 5,296 moles.
1,4 moles carbon monoxide are produced.
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
The answer is 7,829.10 ex.23 atoms.

The equivalence is 1992 moles.
2,55 moles of the compound CO have 71,4 grams.
10.08 moles (there are six carbon atoms per molecule of C6H6, hence, six times the number of moles of carbon can be produced).

The atomic mass of carbon, C is 12.0Amount of C = mass of sample/molar mass = 0.170/12.0 = 0.0142mol There are 0.0142 moles of carbon in a 0.170g pure sample.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
The answer is 10 moles of carbon monoxide.2 C + O2 = 2 CO
