Henry's law constant for `CO_(2)` in water is `1.67xx10^(8) Pa` at `298 K`. Calculate the quantity of `CO_(2)` in `500mL` of soda water when packed under `2.5 atm CO_(2)` pressure at `298 K`.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Convert Pressure from Atmospheres to Pascals
Given that the pressure of CO₂ is 2.5 atm, we need to convert this to Pascals using the conversion factor \(1 \text{ atm} = 1.01 \times 10^5 \text{ Pa}\).

\[ P = 2.5 \, \text{atm} \times 1.01 \times 10^5 \, \text{Pa/atm} = 2.5 \times 1.01 \times 10^5 \, \text{Pa} = 2.525 \times 10^5 \, \text{Pa} \]
