**Problem 9: Decomposition of Hydrogen Peroxide**

Hydrogen peroxide is a common compound that readily decomposes if left out for too long. In this experiment, a sample of the aqueous solution decomposes, and the oxygen produced is collected via water displacement using a gas collection tube. The collected data is displayed in the table below.

**Chemical Reaction:**
\[ 2 \text{H}_2\text{O}_2 (\text{aq}) \rightarrow 2 \text{H}_2\text{O} (\text{l}) + \text{O}_2 (\text{g}) \]

**Data:**

| Parameter                     | Value       |
|-------------------------------|-------------|
| Atmospheric Pressure          | 758.99 torr |
| Temperature                   | 22.8°C      |
| Vapor Pressure of Water (at 22.8°C) | 20.815 torr |
| Volume of Gas Collected       | 193.6 mL    |

**Questions:**

a. What is the partial pressure of \(\text{O}_2 (\text{g})\) produced in the decomposition?

b. How many moles of \(\text{O}_2 (\text{g})\) were produced in the decomposition?

c. Calculate the experimental mass of \(\text{H}_2\text{O}_2\) that would need to decompose in order to form this amount of oxygen.
