A piece of dry ice , `CO_(2)` is placed in a test tube , which is then sealed off. If the mass of dry ice is 0.36 g and the sealed test tube has a volume of `20 cm^(3)` , what is the final pressure of the `CO_(2)` in the tube if all the `CO_(2) ` vaporise and reached thermal equilibrium with the surrounding at `27^(@)C` ?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Convert the volume from cm³ to liters
The volume of the test tube is given as 20 cm³. To convert this to liters, we use the conversion factor \(1 \, \text{cm}^3 = 10^{-3} \, \text{L}\).

\[ V = 20 \, \text{cm}^3 = 20 \times 10^{-3} \, \text{L} = 0.020 \, \text{L} \]
