Answer. There are 6 carbon atoms/molecule of glucose. Avogadro's constant (6.02 * 10^23) represents the number of atoms/molecules in a mole (atoms if it is a pure substance). It is required to takes place in considering 6.022x10^23 molecules.

A mole is equal to 6.022 X 1023 atoms or molecules, whichever is the primary unit used to create the mole.

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.

which I make to be 1.748*10^22 molecules. Quite a few! But then they are quite small. Structurally, the glucose molecule is a 6 membered ring with an overall molecular size of roughly 1nm as measured by the long axis of the cyclic form.

A carbon dioxide molecule, which has the formula CO2, contains one carbon atom and two oxygen atoms. This information is contained in the subscripts after each element. A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.

A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms. The subscripts also indicate the ratios of the elements. A dozen CO2 molecules have one dozen carbon atoms and two dozen oxygen atoms.
