    Answer: 11.5 moles of carbon

    Explanation:

    Based on Avogadro's law:

    1 mole of any substance has 6.02 x 10^23 atoms

    So, 1 mole of carbon = 6.02 x 10^23 atoms

    Z moles = 6.93 x 10^24 atoms

    To get the value of Z, cross multiply:

    (6.93 x 10^24 atoms x 1mole) = (6.02 x 10^23 atoms x Z moles)

    6.93 x 10^24 = (6.02 x 10^23 x Z)

    Z = (6.93 x 10^24) ➗ (6.02 x 10^23)

    Z = 1.15 x 10

    Z = 11.5 moles

    Thus, there are 11.5 moles of carbon.
