`60 cm^(3)` of oxygen was added to `24 cm^(3)` of carbon monoxide and the mixture ignited. Calculate :
the volume of oxygen used up.

Explanation

To solve the problem of calculating the volume of oxygen used up when 60 cm³ of oxygen is added to 24 cm³ of carbon monoxide and ignited, we can follow these steps:

### Step 1: Write the balanced chemical equation
The reaction between carbon monoxide (CO) and oxygen (O₂) produces carbon dioxide (CO₂). The balanced chemical equation for this reaction is:

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

### Step 2: Determine the stoichiometry of the reaction
