50 " mL of " pure and dry `O_2` was subjected to silent electric discharge and on cooling to the original temperature, the volume of ozonised oxygen was found to be 47 mL The gas was brought into contact with turpentine oil, after absorption of `O_3`, the remaining gas occupied 41 mL volume. What is the molecular formula of ozone?

Explanation

To solve the problem, we need to determine the molecular formula of ozone (O₃) based on the given data. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Initial Conditions
We start with 50 mL of pure and dry O₂. After subjecting it to silent electric discharge, the volume of ozonized oxygen is found to be 47 mL.

### Step 2: Determine the Volume of Ozone Formed
The volume of O₂ that reacted to form ozone can be calculated by finding the difference between the initial volume and the volume after the reaction:
- Initial volume of O₂ = 50 mL
