Answer :
One mole of the glucose molecule (C6H12O6) would yield six moles of carbons atoms, due to there being six of them per molecule. Multiply the moles of glucose present, 0.1 moles in this case, by the number of carbon atoms per molecule, six, to get 0.6 moles of carbon, which translates into about 3.61×10^23 carbon atoms. (that’s what they said)
