Calculate the pressure exerted by `22g` of `CO_(2)` in `0.5 dm^(3)` at `300 K` using (`a`) the ideal gas law and (`b`) the van der Waals equation. Given `a=300.0 kPa dm^(6) mol^(-2)` and `b=40.0 cm^(3) mol^(-1)`.

Explanation

To solve the problem of calculating the pressure exerted by 22 g of CO₂ in a volume of 0.5 dm³ at a temperature of 300 K using both the ideal gas law and the van der Waals equation, we will follow these steps:

### Part (a): Using the Ideal Gas Law

1. **Identify the given values:**
- Mass of CO₂ (W) = 22 g
- Molar mass of CO₂ = 44 g/mol
- Volume (V) = 0.5 dm³
