A vessel contains X number of molecule of hydrogen gas at a certain temperature and pressure. How many molecules of oxygen will be present in a vessel of same volume under the same conditions of temperature and pressure? Name the law to justify your answer.

Explanation

To solve the problem, we need to determine how many molecules of oxygen will be present in a vessel of the same volume under the same conditions of temperature and pressure, given that there are X molecules of hydrogen gas in another vessel.

### Step-by-Step Solution:

1. **Understanding the Given Information**:
- We have a vessel containing X molecules of hydrogen gas (H₂).
- We need to find out how many molecules of oxygen gas (O₂) will be present in a vessel of the same volume under the same conditions of temperature and pressure.
