Calculate the density of `CO_(2)` gas which has pressure 745 mm at `65^(@)C.`

Explanation

To calculate the density of CO₂ gas under the given conditions, we can use the ideal gas equation and rearrange it to find density. Here’s a step-by-step solution:

### Step 1: Write down the ideal gas equation
The ideal gas equation is given by:
\[ PV = nRT \]
Where:
- \( P \) = pressure
- \( V \) = volume
