Find the volume of oxygen at S. T.P. required. for the complete combustion of 2 litres of carbon monoxide at S.T.P.

Explanation

To find the volume of oxygen at standard temperature and pressure (S.T.P.) required for the complete combustion of 2 liters of carbon monoxide (CO), we can follow these steps:

### Step 1: Write the balanced chemical equation for the combustion of carbon monoxide.
The balanced equation for the combustion of carbon monoxide is:
\[ \text{2 CO} + \text{O}_2 \rightarrow \text{2 CO}_2 \]

### Step 2: Determine the stoichiometry of the reaction.
From the balanced equation, we can see that 2 moles of carbon monoxide react with 1 mole of oxygen. Therefore, the ratio of CO to O2 is 2:1.
