Both carbon monoxide (CO) and carbon dioxide `(CO_(2))` are binary compounds of carbon and oxygen. Show by calculations that both the compounds contain different percentages of the two elements. [R.A.M.: C = 12, O = 16.]

Explanation

To show that carbon monoxide (CO) and carbon dioxide (CO₂) contain different percentages of carbon and oxygen, we will calculate the percentage by mass of each element in both compounds using the formula:

\[ \text{Percentage by mass of an element} = \left( \frac{\text{Mass of the element in the compound}}{\text{Molecular mass of the compound}} \right) \times 100 \]

### Step 1: Calculate the molecular mass of Carbon Dioxide (CO₂)
