    No of moles of Carbon, C = mass / molar mass.

    Molar mass of carbon = 12.0107. We only have to calculate the no of moles

    of carbon to obtain carbon's mass ...

    From Sucrose chemical formula C12H22O11 we know that there are 12

    carbon atoms.

    So there are 1.4x10^ (20) x12 = 16.8 x 10^20 carbon atoms.

    We will use avogardo's number to find out the number of carbon molecules

    in the compound.

    From Avogadro's no. One mole of any substance equals to 6.022140857

    atoms.

    So X mole contains 16.8 * 10^ (20) carbon atom

    (16.8x10^20 carbon atoms) / 6.022 x10^23 particles/mol = 0.00279 mols

    The molar mass of carbon is 12.0107g/mol so we'll multiply to get the mass:

    0.00279 mols x 12 = 0.03348.
