    1 mole of anything is the Avogadro number of them = 6.022 x 10^23.

    1 mole of Ibuprofen contains 13 moles of C atoms = 13 x 6.022 x 10^23 atoms. = 78.286 x 10^23

    Number of moles of Ibuprofen containing 1.23 x 10^23 atoms of carbon

    1.23 x 10^23 / 78.286 x 10^23 = 0.0157 moles Ibuprofen.
