Write the equations, see how many moles of CO2 will be produced, use some gas equation(maybe the perfect gas equation) to calculate how much volume that occupies at this pressure.

perfect gas equation

For the record - in English it is called the ideal gas equation.

Haha, true that. Translating things literally is bound to fail.
I also saw there's a difference in english, with perfect gases being these that do not change their cp and cv with temp/pressure.
