Compute the volume of methane gas that must be burnt completely to produce 100 L of `CO_(2)` at STP.

Explanation

To compute the volume of methane gas (CH₄) that must be burnt completely to produce 100 L of carbon dioxide (CO₂) at STP, we can follow these steps:

### Step 1: Write the balanced chemical equation for the combustion of methane.
The combustion of methane can be represented by the following balanced equation:

\[ \text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O} \]

### Step 2: Determine the mole ratio from the balanced equation.
