Answer:
= 72.73%
Explanation:
The percentage by mass of an element is given by;
% element = total mass of element in compounds/molar mass of compound × 100
The mass of oxygen in carbon dioxide = 32 g
Molar mass of CO2 = 44 g
Therefore;
% of O2 = 32/44 × 100%
<u>= 72.73%</u>

It seems that you have missed the given options for this question, but anyway, the correct answer is NONE OF THE ABOVE. None of the molecules given must be shown with resonance structures. A resonance structure is defined as the way or presenting <span>delocalized electrons within certain molecules or polyatomic ions. This bonding cannot be expressed by one single Lewis </span><span>structure. Hope this answer helps.</span>
