The problem is incomplete. However, there can only be two probable questions for this problem. First, you can be asked the individual partial pressures of each gas. Second, you can be asked the volume occupied by each gas. I can answer both cases for you.

1.

Let's assume ideal gas.

Pressure for N₂: 2 bar*0.4 = 0.8 bar

Pressure for CO₂: 2 bar*0.5 = 1 bar

Pressure for CH₄: 2 bar*0.1 = 0.2 bar

2. For the volume, let's find the total volume first.

V = nRT/P = (1 mol) (8.314 J/mol-K) (30 + 273 K) / (2 bar*10⁵ Pa/1 bar)

V = 0.0126 m³

Hence,

Volume for N₂: 0.0126 bar*0.4 = 0.00504 m³

Volume for CO₂: 0.0126*0.5 = 0.0063 m³

Volume for CH₄: 0.0126*0.1 = 0.00126 m³
