Deviation of real gases from ideal behaviour can be studied by plots of compressibility factor (Z) vs p. The copressibility factor is
`Z=(pV)/(nRT)`
The compressibility factor for 1 mole of a gas obeying van der Waals gas equation at `0^(@)C` and 100 atm pressure is found to be 0.5. The van der Waals gas equation is
`(p(an^(2))/(V^(2)))(V-nb)=nRT`
What is the volume of the gas?

Explanation

To find the volume of the gas using the given information, we will follow these steps:

### Step 1: Write down the formula for the compressibility factor (Z)
The compressibility factor is defined as:
\[ Z = \frac{pV}{nRT} \]
Where:
