A vessel of capacity 10 litres contains 0.5 moles of `CO_(2)`, 1.3 moles ofnitrogen and 0.20 mole of oxygen at `30^(@)C`. Assuming the gases to be ideal, find the pressure of the mixture , R `= 8.31 J m o l^(-1) K^(-1)`.

Explanation

To find the pressure of the gas mixture in the vessel, we can use the Ideal Gas Law, which is given by the equation:

\[ P = \frac{nRT}{V} \]

Where:
- \( P \) = pressure (in Pascals)
- \( n \) = total number of moles of gas
- \( R \) = ideal gas constant (8.31 J/(mol·K))
