An industrial process requires the complete combustion of carbon monoxide gas. An enriched gas mixture containing 15%15\%15% oxygen by volume is used for this process.

Calculate the volume of this gas mixture, in dm3\text{dm}^3dm3, needed to react completely with 13.5 dm313.5\text{ dm}^313.5 dm3 of carbon monoxide gas.

The balanced chemical equation for the reaction is: 2CO(g)+O2(g)→2CO2(g)2\text{CO(g)} + \text{O}_2\text{(g)} \rightarrow 2\text{CO}_2\text{(g)}2CO(g)+O2​(g)→2CO2​(g)
