A sample of carbon dioxide occupies `30 "cm"^3` at `15^@C` and 740 mm pressure. Find its volume at STP.

Explanation

To find the volume of carbon dioxide at Standard Temperature and Pressure (STP), we can use the ideal gas law in the form of the combined gas law, which relates the initial and final states of a gas. The formula we will use is:

\[ \frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2} \]

### Step 1: Identify the given values
- Initial volume, \( V_1 = 30 \, \text{cm}^3 \)
