According to the question, the correct answer is 70%. If the question is changed to 60 ml of 0.5M NaOH, only then the answer will be 56%. @Azhaghu Roopesh M , please correct the question.

You have compound \text{compound} spelled correctly in the body of your problem but not in the title. Compund \text{Compund} should be fixed to compound \text{compound} , just to have it be more professional. Otherwise, gnarly problem dude!
