The volume of gas formed by the interaction of 17 liters of carbon monoxide with an excess of oxygen is …

The reaction of the formation of carbon dioxide.
2CO + O2 = 2CO2.
The number of moles of carbon monoxide.
n (CO) = V / Vm = 17 L / 22.4 mol / L = 0.75 mol.
It follows from the reaction equation that the number of moles of gases will be equal. This means that the volume of the released gas will be the same.
