Question 41

Hydrogen peroxide decomposes to make oxygen.

2H2O2→2H2O+O22\text{H}_2\text{O}_2 \rightarrow 2\text{H}_2\text{O} + \text{O}_22H2​O2​→2H2​O+O2​

The desired product is oxygen.

Relative atomic masses: H=1\text{H} = 1H=1, O=16\text{O} = 16O=16.

Calculate the atom economy of this process for oxygen.

Give your answer as a percentage.
