#### Answer:

#### Explanation:

The percent yield can be calculated by:

The actual yield of oxygen is given and it is

We will need to find the theoretical yield.

The decomposition reaction of water can be written as:

To find the theoretical yield of oxygen we will use dimensional analysis:

Thus, the theoretical yield is equal to

The percent yield is then:
