Hydrogen and oxygen are combined in the ratio of 1 : 16 by mass in hydrogen peroxide. What is the percentage compostion of hydrogen peroxide ?

Text Solution

Verified by Experts

The correct Answer is:
Oxygen = 94.15 %, Hydrogen = 5.88 %
Percentage of oxygen in `H_(2)O_(2)=((32u))/((34u))xx100=94.12%`
Percentage of hydrogen in `H_(2)O_(2)=((2u))/((34u))xx100=5.88%`.
