In a combustion chamber, ethane $\left({\mathrm{C}}_2{\mathrm{H}}_6\right)$ is burned at a rate of $6\mathrm{kg}/\mathrm{h}$ with air that enters the combustion chamber at a rate of $176\mathrm{kg}/\mathrm{h}$. Determine the percentage of excess air used during this process. Use data from the tables. The percentage of excess air used during this process is $\%$.
