1. The Ideal Gas Law

The Ideal Gas Law is:

PV = nRT

Where:

* P = Pressure (in Pascals)

* V = Volume (in cubic meters)

* n = Number of moles

* R = Ideal Gas Constant (8.314 J/mol·K)

* T = Temperature (in Kelvin)

2. Convert Units

* Pressure: Convert kPa to Pascals: 204.67 kPa * 1000 Pa/kPa = 204670 Pa

3. Rearrange the Ideal Gas Law to Solve for Volume (V)

V = (nRT) / P

4. Plug in the Values

V = (0.08 mol * 8.314 J/mol·K * 300 K) / 204670 Pa

5. Calculate the Volume

V ≈ 0.00097 m³

6. Convert to a More Convenient Unit

* Cubic meters to liters: 0.00097 m³ * 1000 L/m³ ≈ 0.97 L

Therefore, you would need approximately 0.97 liters to store 0.08 moles of helium gas at 204.67 kPa and 300 K.
