A 2 L flask contains 22 g of carbon dioxide and 1 g of helium at `20^(@)C` . Calculate the partial pressure exerted by `CO_(2)` and He if the total pressure is 3 atm.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the number of moles of Carbon Dioxide (CO₂)
The formula to calculate the number of moles is:
\[ n = \frac{\text{mass}}{\text{molar mass}} \]
For CO₂:
...
