Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Total percentage composition in a compound is: \[ \text{Hydrogen \% + Oxygen \% = 100} \]
Step 1: Given hydrogen percentage. \[ \text{Hydrogen} = 11.1\% \]
Step 2: Calculate oxygen percentage. \[ \text{Oxygen} = 100 - 11.1 = 88.9\% \]
Step 3: Conclusion. \[ \text{Oxygen percentage = 88.9\%} \]
