V(O2)=25л

V(CO2)-?

V(CO2) -?

It seems like you are providing an equation related to the volume of oxygen consumed (V(O2)) and the volume of carbon dioxide produced (V(CO2)). However, the equation you have given is not complete. To calculate the volume of carbon dioxide produced (V(CO2)), we need more information or the complete equation.

If you could provide more details or the full equation, I would be happy to help you calculate the volume of carbon dioxide produced.
