Answer:

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.
