    24

    Step-by-step explanation:

    Let's make a table of valence electrons and add them up.

    Atom Electrons

    1 C 1 * 4 = 4

    3 O 3 * 6 = 18

    +2e⁻ 2 = 2

    TOTAL = 24

    The Lewis structure below shows that there are eight electrons in covalent bonds and 16 electrons in lone pairs.
