One mole each of hydrogen, oxygen and nitrogen are mixed in a close container of volume `10` L and temperature `27^(@)C.` Calculate the pressure exerated by the mixture. `(R=.314Jmol^(-1)K^(-1))`

Explanation

To calculate the pressure exerted by the mixture of gases (hydrogen, oxygen, and nitrogen) in a closed container, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values**:
- Number of moles of hydrogen (n1) = 1 mole
- Number of moles of oxygen (n2) = 1 mole
- Number of moles of nitrogen (n3) = 1 mole
