Given information
The element that has the highest mass percent composition in the above mentioned compounds.
Step-by-step explanation
Step 1.
The given compound is 
.
The chemical name of the given compound is carbon monoxide.
The formula to calculate the mass percent composition of an element is,
Where,
-
represents the weight of the element in 
of the compound. -
represents the total weight of the compound.
The above formula shows that the mass percent is directly related to the weight of the element in of the compound.
The atomic weight of carbon is 
.
The atomic weight of oxygen is 
.
Thus, the weight of oxygen is higher than the weight of carbon.
Therefore, oxygen has a higher mass percent composition.
